Question

If q1 andq2 are two charges having equal opposite nature and q1< q2 than a third positive charge particle will be in stable equilibrium at:- (a) a point in region between q1 and q2 iii) a point near q2 and behind it iv) none of the above(b)a point near q1 and before it(c) Demonetisation(d) Privatisation​

Answer 1

Explanation:

the nullpoint is the point where the electric filed (any kind of field) is zero means no net force will act on it thus it's a stable equilibrium point

this can be calculated by equating the forces on the given charge die to the given charges

from that as those two r opposite charges the stae equilibrium point is behind those two charges not in between them and as q1<q2 point is near to q1

this might help u in many ways like conceptually & etc..

object me if there is any mistake in solution
