Figure`6.52` shows a balanced wheatstone net. Now, it is disturbed by changing `P` to `11 Omega`. Which of the following steps will not bring the bridge to balance again?

A

increasing `R` by `2 Omega`

B

increasing `S` by `20 Omega`

C

increasing `Q `by `10 Omega`

D

making product `RQ = 2200 (Omega)^(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
`P//Q = R//S`. If `P` is increased, then either `R` or `Q` should be increased or `S` should be decreased.

In the gives figure , a balanced Wheastone bridge is shown . Now it is distrubed by changing P to 15 Omega . Which of the following steps will not bring the bridge to balance again ?

Figure 6.64 shows a balanced wheatstone bridge.

When a sample of ideal gas is changed from an initial state to a final state, various curves can be plotted for the process like P-V curve, V-T curve,P-T curve etc. For example, P-V curve for a fixed amount of an ideal gas at constant temperature is a rectangular hyperbola, V-T curve for a fixed amount of an ideal gas at constant volume is again a straight line. However, the shapes may vary if the constant parameters are also changed. Now, answer the following questions : Which of the following graphs is not possible for a fixed amount of ideal gas upon moving from initial state A to final state B :

Figure shows the circuit of a potentiometer. The length of the potentiometer wire AB is 50 cm. The emf of the battery E, is 4 volt having negligible internal resistance. Values of resistances R_(1) and R_(2) are 15 ohm and 5 ohm respectively. When both the keys are open, he null point is obtained at a distance of 31.25 cm from end A but when both the keys are closed, the balance length reduces to 5 cm only R_(AB) = 10 Omega Which of the following can be possible way to connect the batteries in the potentiometer setup above ?

The figure below shows a wheatstone bridge with resistors P and Q having almost equal resistance. When R = 400 Omega , the bridge is in balanced condition. If on interchanging P and Q, the bridge is again balanced for R = 405 Omega , then the value of X is

The reaction between phosphorus (P_(4)) and hydrogen (H_(2)) can result in the formation of phosphine (PH_(3)) as shown : P_(4)(s)+6H_(2)(g)hArr 4PH_(3)(g) The graph shows the change in concentration of hydrogen for this reaction in which the system was distrubed after four hours. Which of the following could explain the change in hydrogen concentration at time = 4 hours?

The general motion of a rigid body can be considered to be a combination of (i) a motion of its centre of mass about an axis, and (ii) its motion about an instantaneous exis passing through the centre of mass. These axes need not be stationary. Consider, for example, a thin uniform disc welded (rigidly fixed) horizontally at its rim to a massless, stick as shown in the figure. When the disc-stick system is rotated about the origin on a horizontal frictionless plane with angular speed omega the motion at any instant can be taken as a combination of (i) a rotation of the disc through an instantaneous vertical axis passing through its centre of mass (as is seen from the changed orientation of points P and Q). Both these motions have the same angular speed omega in this case Now consider two similar system as shown in the figure: Case (a) the disc with its face vertical and parallel to x-z plane, Case (b) the disc with its face making an angle of 45^@ with x-y plane and its horizontal diameter parallel to x-axis. In both the cases, the disc is welded at point P, and the systems are rotated with constant angular speed omega about the z-axis. . Which of the following statements about the instantaneous axis (passing through the centre of mass) is correct?
