True or false? the surfaces of equal potential around an infinite charged plane are parallel to the plane (i. e. the surfaces never intersect the charged plane). false true [5 points] suppose i center a conducting sphere of charge (radius r, total charge +q) at the origin. how much energy would it take to move a point charge (total charge +q) from the surface of the sphere (r = r) to the center of the sphere (r = 0)? e = kq / r

While goofing off at the ice skating rink, a student takes off her shoes and places each of them on the ice. her friend, a hockey player, then shoots a hockey puck at each shoe. the first puck immediately comes to rest after it collides with the left shoe. the second puck rebounds after it collides with the right shoe. if each hockey puck has the same incoming speed, which shoe has greater speed after the collision? the right shoe. both shoes have the same speed. the left shoe.
