MHT CET 2025 Physics question
Three charges '+3q', 'Q' and '+q' are placed in a straight line of length '' at points at distances 0, and respectively. The value of Q in order to have the net force on +q to be zero, Q = xq. The value of x is
Answer: (B)
Solution
Net force on +q at distance must vanish. Force from +3q (distance ) is repulsive: . Force from Q (distance ) is and must point towards the +3q side, so Q has to be negative. Taking the
