Question

3. Solve numerical examples.
i. Two small spheres 18 cm apart have
equal negative charges and repel each
other with the force of 6x10 'N. Find the
total charge on both spheres.
[Ans: q = 2.938x10°C]
ii. A charge +q exerts a force of magnitude
-0.2 N on another charge -2q. If they
are separated by 25.0 cm, determine the
value of q.
[Ans: q=0.8333 uC]​
