Question 2

Consider a uniform electric field in the z direction. The potential is not a constant

A on the x-y plane for a given z.

B for any y for a given z.

C for any x for a given z.

D in all space.

Question 3

A +q

B -2q

C (frac { -âˆš2q}{1+âˆš2})

D (frac { k_1d_1+k_2d_2 }{k_1+d_2})

Question 5

A positively charged particle is released from rest in a uniform electric field. The electric potential energy of the charge

A decreases because the charge moves opposite to the electric field.

B decreases because the charge moves along the electric field.

C increases because the charge moves along the electric field.

D remains a constant because the electric field is uniform.

Question 6

If a conductor has a potential V â‰ 0 and there are no charges anywhere else outside, then

A there must be charges inside the surface.

B there must be charges only on the surface.

C there will be some charge in the body of the conductor.

D there must be charges on the surface or inside itself.

Question 7

In a region of constant potential

A the electric field shall necessarily change if a charge is placed outside the region.

B there can be charge inside the region.

C the electric field is zero

D the electric field is uniform

Question 8

A (frac { Q_1+Q_4}{2C})

B (frac { Q_2-Q_3 }{2C})

C (frac { Q_2+Q_3}{2C})

D (frac { Q_1+Q_2+Q_3+Q_4}{2C})

Question 9

For equipotential surfaces, which statement is not correct?

A will be more crowded near regions of large charge densities.

B will be more crowded near sharp edges of a conductor.

C will always be equally spaced.

D are closer in regions of large electric fields compared to regions of lower electric fields.

Question 10

A The work done in figure (iii) is greater than figure (ii) but equal to that in figure (i).

B The work done is the same in figure (i), figure (ii) and figure (iii).

C The work done in figure (ii) is least.

D The work done in figure (i) is the greatest.
