Force Direction Which of the arrows best represents the direction of the net force on charge +Q due to the other two charges? +2 Q +4 Q + Q 1 2 3 4 5 d d
Conducting Sphere A conducting sphere (shown in grey in the drawing) of radius R has a charge q distributed uniformly over its surface. A spherically-shaped Gaussian surface with a radius r < R is represented in the drawing by the dashed circle. Applying Gauss’ law, what is the magnitude of the electric field inside the Gaussian sphere? a ) k q r b ) k q r 2 c ) k rq R d ) 0 e ) k q R
