Electrostatics deals with forces, potentials and fields arising from charges that are:

  1. Static
  2. Steady
  3. Stacked
  4. Stained
Show answer and solution

Correct answer: A. Static

1. The branch is named for the state of the charges it studies. 2. Those charges are not in motion. 3. Electrostatics deals with forces, fields and potentials arising from static charges. 4. So the answer is static. _Source: syllabus Physics, Ch 1 'Electric Charges and Fields'_

Like charges repel and unlike charges:

  1. Amplify
  2. Attract
  3. Absorb
  4. Annul
Show answer and solution

Correct answer: B. Attract

1. Two kinds of electrification exist. 2. Their behaviour towards each other is opposite. 3. Like charges repel and unlike charges attract each other. 4. So the answer is attract. _Source: syllabus Physics, Ch 1 'Electric Charges and Fields'_
