We levitate a negatively charged oil droplet between two charged plates. If the weight of a charged sphere (e-) of mass 1.1 x 10-14 kg is balanced by an electric field of 1.68 x 105 N/C , how many excess electrons are on the sphere.

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
