Object to remain motionless above the charged plane

Reference no: EM13540817

An object with mass m = 1.1 g and charge q is placed at point A, which is 0.05 m above an infinitely large, uniformly charged, nonconducting sheet (? = -5.4 10-5 C/m2), as shown in the figure. Gravity is acting downward (g = 9.81 m/s2). Determine the number, N, of electrons that must be added to or removed from the object for the object to remain motionless above the charged plane.
