Asmall sphere with mass mcarries a positive chargeqand is attached to one end of a silk fiber of lengthl. the other end of the fiber is attached to a large vertical insulating sheet that has a positive surface charge densityσ.
a) find the magnitude and direction of the electric force on the sphere
b) show that when the sphere is in equilibrium, the fiber makes an angleθequal to arctan (qσ/2mgε0) with the vertical sheet. gis the acceleration due to gravity.
