Question

1. how many electrons must be removed from a sphere to giveit a charge of +5.92 nC? b. the electric force acting on a proton is(.23*10^-16N, 252 degrees). What is the direction of the electricfield at this point? c. A charge of -36 nC is at the origin of coordinates. What isthe direction of E due to this charge at the point (-20 cm, +20cm)? 1. how many electrons must be removed from a sphere to giveit a charge of +5.92 nC? b. the electric force acting on a proton is(.23*10^-16N, 252 degrees).

Explanation / Answer

1.a. no. of electrons to be removed = 5.92 x10^-9 /1.602x10^-19                                                      = 3.695x10^10                b. force acting on a proton will be in the same direction of theelectric field at the point. c. at 315 degrees i.e. in the fourth quadrant.
