Question

In the figure if net force on q is zero then value of Q/q is

A) √2

B) 2√2

C) 1/2√2

D) 1/√2

Answer 1

The correct option is B) 2√2.

Net force on Q is zero , it means Q and q are in opposite nature .

Let Q is positive nature and q is negative nature Then, force between Q and Q will be repulsion, And force between Q and q will be attraction,

Now, net force act on Q = net force act by q - net force act by Q on Q = 0

Net force act by q on Q = net force act by Q on Q
