Directions : In the following question more than one of the answers given may be correct. Select the correct answer and mark it according to the code:
Three charged particles are collinear and are in equilibrium. Then: (1) all the charged particles cannot have the same polarity (2) all the charged particles have the same polarity (3) the equilibrium is stable (4) the equilibrium is unstableA) 1 and 2 are correct
B) 2 and 3 are correct
C) 1 and 4 are correct
D) 1, 2 and 3 are correct
Correct Answer: A
Solution :
If a charged panicle is in equilibrium under electrostatic force, then that particle never be in stable equilibrium. Also since, all the charges are in equilibrium so, net force on any one of charges should be zero. For this two equal and opposite forces will act on any charge.
