Given that,
First charge = q
Second charge = 9q
Distance = 16 m
Let the third charge q be placed at a distance x from q and hence its distance from 9q and (16−x) cm.
We need to calculate the electric force for first charge
Using formula of electrostatic force
Put the value into the formula
We need to calculate the electric force for second charge
Using formula of electrostatic force
Put the value into the formula
We need to calculate the value of x
Using formula of net electrostatic force
Put the value into the formula
We need to calculate the distance of point charge from second charge
Using formula for distance
Put the value of x
Hence, The net electrostatic force will be zero at 4 cm from first charge and 12 cm from second charge.
