Acharge of -6.50 nc is spread unifonnly over the surface of one face of a nonconducting disk of radius 1.25 cm. (a) find the
magnitude and direction of the electric field this disk produces at a point p on the axis of the disk a distance of 2.00 cm from its center. (b) suppose that the charge were all pushed away from the center and distributed unifonnly on the outer rim of the disk. find the magnitude and direction of the electric field at point p. (c) if the charge is all brought tn the center of the disk, find the magnitude and direction of the electric field at point p. (d) why is the field in part (a) stronger than the field in part (b)? why is the field in part (c) the strongest of the three fields?

A60-kg box is being pushed a distance of 6.8 m across the floor by a force p with arrow whose magnitude is 162 n. the force p with arrow is parallel to the displacement of the box. the coefficient of kinetic friction is 0.24. determine the work done on the box by each of the four forces that act on the box. be sure to include the proper plus or minus sign for the work done by each force. (the floor is level and horizontal. forces that act on the box: pushing force p, frictional force f, normal force n, and weight mg.)
