Charge is distributed non uniformly on a sphere such that volume charge density is given as p = ar where a = 8 uc/m^4 and 0 < r < R. Radius of the sphere is R = 75 cm. Find the total charge in the sphere.

An electron initially at rest falls a distance of 1.5cm in a uniform electric field of magnitude 2×10^4N/C. The time taken by the electron to fall this distance is
