l is length of silk thread.
A charged particle of radius 5×10^−7 m is located in a horizontal electric field of intensity 6.28 × 10^5 V/m. The surrounding medium has the coeffiecient of viscosity η = 1.6 × 10^5 Ns/m^2. The particle starts moving under the effect of electric field and finally attains a uniform horizontal speed of 0.02 m/s. Find the number of electrons on it. Assume gravity free space.

Two identical charged spheres suspended from a common point by two mass-less strings of length l are initially at a distance d ( d<<l) apart because of their mutual repulsion . The charge begins to leak from both the spheres at a constant rate. As a result the charge approach each other with a velocity v. Then as a function of distance x between them .
