You will find it difficult to recap the pen since u lost your Stereopsis. 1.)Force become one fourth.

When sphere 3 touches 1 the charge on both becomes Q/2. When sphere 3 the touches sphere 2 the charge on each becomes (Q + Q/2)/2 = 3Q/4. The force between sphere 1 and 2 is then F = C(Q/2)(3Q/4) = (3/8)CQQ = (3/8)F = 0:033N: Originally F= CQQ
= 0:088 N, where C is a constant. When sphere 3 touches 1 the
charge on both becomes Q/2. When sphere 3 the touches sphere 2 the charge on each becomes
(Q + Q/2)/2 = 3Q/4. The force between sphere 1 and 2 is then
F = C(Q/2)(3Q/4) = (3/8)CQQ
= (3/8)F = 0:033N:
