Question

ID: C charge is 10 m from a -20 C charge. The electrostatic force on the positive charge ow towand the negative charge D) 90x 10 N away from the negative chag Name: A) 90x 10 C 90 x 10'N E) none of these N toward the negative charge B) 90 10'N away from the negative charge negati 2. The diagram shows the electric field lines due to two charged parallel metal planes We conclude that A) the upper plate is positive and the lower plate is negative B) a proton at X would experience the same force it it wee placed at Y C) a proton at X experiences a greater force than if it were placed at Z )a proton at X experiences less force than if it were placed at Z E) an eloctron at X could have its weight balanced by the electrical force

Explanation / Answer

Solving 1st question

Force=K*q1*q2/r^2

Putting values

Force=9*10^9*10/100=9*10^8 N

Direction toward negative charge
