Imagine that an uncharged pith ball is brought into the electrostatic field of a charged rod. the side of the pith ball closest to the negatively charged end of the rod will a. not experience any induced charge and remain neutral. b. be given a positive charge produced by the movement of electrons to the other end of the ball. c. be given a negative charge produced by the movement of electrons from the rod. d. be given a negative charge produced by the movement of electrons from the other end of the ball.

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 710 n/m. it is initially at rest on an inclined plane that is at an angle of θ = 23° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk = 0.19. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. a) what is the block's initial mechanical energy? b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
