  1. Question 1

    Electrostatics is a branch of physics which deals with the study of:

    • Acharges in motion
    • Bcharges at rest
    • Cmagnetic fields
    • Dheat energy
    Show answer

    Answer: B

    Electrostatics deals with the study of charges at rest.

  2. Question 2

    A plastic comb rubbed through dry hair and brought near small pieces of paper:

    • Arepels them
    • Bhas no effect on them
