Describe schematically the equipotential surfaces corresponding to
(a) a constant electric field in the z-direction,
(b) a field that uniformly increases in magnitude but remains in a constant (say, z) direction,
(c) a single positive charge at the origin, and
(d) a uniform grid consisting of long equally spaced parallel charged wires in a plane.

Text Solution

Verified by Experts

(a) Planes parallel to x-y plane.
(b) Same as in (a), except that planes differing by a fixed potential get closer as field increases.
(c) Concentric spheres centred at the origin.
(d) A periodically varying shape near the grid which gradually reaches the shape of planes parallel to the grid at far distances.

A particle of charge q moves with velocity vec(v) along positive y - direction in a magnetic field vec(B) . Compute the Lorentz force experienced by the particle (a) when magnetic field is along positive y-direction (b) when magnetic field points in positive z -direction (c ) when magnetic field is in zy - plane and making an angle theta with velocity of the particle.

A copper wire bent in the shape of a semicircle of radius r translates in its plane with a constant velocity v. A uniform magnetic field B exists in the direction perpendicular to the plane of the wire. Find the emf induced between the ends of the wire if (a) the velocity is perpendicular ot the diameter joining free ends, (b) the velocity is parallel to this diameter.

A square loop of side 12 cm with its sides parallel to X and Y axes is moved with a velocity of 8cms^(-1) in the possitive x-direction in an environment containing a magnetic field in the positive z- direction. The field is neither uniform in space nor constant in time. It has a gradient of 10^(-3)Tcm^(-1) along the negative x-direction (that is it increases by 10^(-3)T as one moves in the negative x-direction), and it is decreasing in time at the rate of 10^(-3)Ts^(-1) . Determine the direction and magnitude of the induced current in the loop of its resistance is 4.50mOmega .

Figure. gives a speed-time graph of a particle in motion along a constant direction. Three equal intervals of time are shown. In which interval is the average acceleration greatest in magnitude ? In which interval is the average speed greatest ? Choosing the positive direction as the constant direction of motion, give the signs of v and a in the three intervals. What are the accelerations at the points A, B, C and D ?

In a certain region of space, electric field is along the z-direction throughout. The magnitude of electric field is, however, not constant but increases uniformly along the positive z- direction, at the rate of 10^5 NC^(-1) per metre. What are the force and torque experienced by a system having a total dipole moment equal to 10^(-7) Cm in the negative Z-direction?

a. The top of the atmosphere is at about 400 kV with respectto the surface of the earth, corresponding to an electric field that decreases with altitude. Near the surface of the earth, the field is about 100 Vm^(-1). Why then do we not get a electric shock as we step out of our house into the openy (Assume the house to be a steel cage so there is no field inside!) b. A man fixes outside his house one evening a two metre high insulating slab carrying on its top a large aluminium sheet of area 1m^(2) . Will he get an electric shock if he touches the metal sheet next morning? c. The discharging current in the atmosphere due to the small conductivity of air is known to be 1800A on an average over the globe. Why then does the atmosphere not discharge itself completely in due course and become electrically neutral? In other words, what keeps the atmosphere charged? d. What are the forms of energy into which the electrical energy of the atmosphere is dissipated during a lightning? (Hint: The earth has an electric field of about 100 Vm^(-1) at its surface in the downward direction, corresponding to a surface charge density =-10^(-9) Cm^(-2) ?.
