The figure below shows a hemispherical insulating cup of inner radius R that carries a total charge q uniformly distributed over its surface. If the charge q = 43.40 μC and R = 21.40 cm, find the electric field at point P in the center of the cup
do you know the formula for getting the electricfield?
formula is Ep=Kq1/d^2 where K is constant and d is distance
