A fully charged capacitor has a capacitance· C. It is discharged through a small ,coil of - resistance wire embedded in a thermally insulated block of specific heat capacity s and mass. If the temperature of the block is raised by `Delta`T, the potential difference V across the capacitance is ...... .

A

`(msDeltaT)/(C)`

B

`sqrt((2msDeltaT)/(C))`

C

`sqrt((2mCDeltaT)/(s))`

D

`(mCDeltaT)/(s)`

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
The energy stored in the capacitor = Heat energy gained by the block
`:. (1)/(2) CV^(2) = msDeltaT`
`:. V^(2)= (2msDeltaT)/(C)`
`:. V =sqrt((2msDeltaT)/(s))`

A parallel plate capacitor with circular plates of radius 1 m has a capacitance of 1 nF. At t = 0, it is connected for charging in series with a resistor R = 1 M Onega across a 2V battery. Calculate the magnetic field at a point P, halfway between the centre and the periphery of the plates, after t=10^(-3)s . (The charge on the capacitor at time t is q (t) = CV [1 - exp (-t//tau) ], where the time constant tau is equal to CR.)

Figure 8.6 shows a capacitor made of two circular plates each of radius 12 cm, and separated by 5.0 cm. The capacitor is being charged by an external source (not shown in the figure). The charging current is constant and equal to 0.15A. (a) Calculate the capacitance and the rate of change of potential difference between the plates. (b) Obtain the displacement current across the plates. (c) Is Kirchhoff’s first rule (junction rule) valid at each plate of the capacitor? Explain.

A parallel plate capacitor with circular plates of radius 0.8 m has a capacitance of 1 nF. At t = 0, it is connected for charging in series with a resistor R = 1 M Omega across a 4V battery. Calculate the magnetic field at a point P, halfway between the centre and the perpendicular of the plates after t=10^(-3)s . (The charge on the capacitor at time t is q (t) = CV [1 - exp (-t//tau) ], where the time constant tau is equal to CR.)

An ideal monoatomic gas is confined in a cylinder by a spring-loaded piston of cross-section 8.0xx10^-3m^2 . Initially the gas is at 300K and occupies a volume of 2.4xx10^-3m^3 and the spring is in its relaxed (unstretched, unompressed) state, fig. The gas is heated by a small electric heater until the piston moves out slowly by 0.1m. Calculate the final temperature of the gas and the heat supplied (in joules) by the heater. The force constant of the spring is 8000 N//m , atmospheric pressure is 1.0xx10^5 Nm^-2 . The cylinder and the piston are thermally insulated. The piston is massless and there is no friction between the piston and the cylinder. Neglect heat loss through lead wires of the heater. The heat capacity of the heater coil is negligible. Assume the spring to be massless.

Answer carefully: (a) Two large conducting spheres carrying charges Q_(1) and Q_(2) are brought close to each other. Is the magnitude of electrostatic force between them exactly given by Q_(1),Q_(2)//4pi epsilon_(0)r^(2) , where r is the distance between their centres? (b) If Coulomb’s law involved 1//r^(3) dependence (instead of would Gauss’s law be still true ? (c) A small test charge is released at rest at a point in an electrostatic field configuration. Will it travel along the field line passing through that point? (d) What is the work done by the field of a nucleus in a complete circular orbit of the electron? What if the orbit is elliptical? (e) We know that electric field is discontinuous across the surface of a charged conductor. Is electric potential also discontinuous there? (f) What meaning would you give to the capacitance of a single conductor? (g) Guess a possible reason why water has a much greater dielectric constant (= 80) than say, mica (= 6).

Three copper blocks of masses M_1, M_2 and M_3 kg respectively are brought into thermal contact till they reach equilibrium. Before contact they were at T_1, T_2, T_3 (T_1 gt T_2 gt T_3) . Assuming there is no heat loss to the surroundings, the equilibrium temperature T is (s is specific heat of copper)
