For a charged solid metal sphere with total charge q and radius r centered on the origin: select "true" or "false" for each statement. the electric field near the metal surface on the outside is perpendicular to the surface. the net charge on the inside of the solid metal sphere is negative. if the solid sphere is an insulator (instead of metal) with net charge qq, the electric field for r > > r would be the same as that of a conductor with the same shape and charge. if the solid sphere is an insulator (instead of metal) with net charge qq, the net charge on the inside of the solid sphere is negative. the electric field for the metal sphere at r < < r will be the same as the field of a point charge, q, at the origin. the electric field inside the solid metal sphere is never zero

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 740 n/m. it is initially at rest on an inclined plane that is at an angle of theta= 26 with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is uk = 0.17. 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. the block's initial mechanical energy is 9.472 j.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.
