Hints and Solutions of Physics Electrostatics MCQ Test Series – Set 3 (Q. No.21–30)

https://www.indiastudysolution.com

Answer 21:b. Answer 22: d.

Answer 23: c

(Hint: Both the spheres can be charged equally. Because for metallic sphere either solid or hollow, the charge will raised on the sphere. Since, both spheres have same surface area, so they can hold equal maximum charge)

Answer 24: a. Answer 25: b. Answer 26: c.

Answer 27: d (Hint: As conductor has positive charge. So, there is deficiency of electrons).

Answer 28: a.

Answer 29: a

(Hint: As revolving charge is equivalent to a current,
So,

 Answer 30: d.
