Expert Answer
Part-(a)
Magnitude of electrostatic force F between tw spheres
where K = 1/ ( 4 π εo ) = 9 × 109 is Coulomb's constant , q's are charge magnitudes on sphere
and r is distance between centres of spheres.
-----------------------------
Part-(b)
Force on second sphere due to first sphere is same as the force on first sphere due to second sphere.
One sphere has +ve charge and other has -v charge, both have equal attractive force towards other
