Aparticle is to move in an xy plane, clockwise around the origin as seen from the positive side of the z axis. in unit vector notation, what torque acts on the particle if the magnitude of its angular momentum about the origin is (a) 4.0 kg x m^2/s, (b) 4.0t^2 kg x m^2/s, (c) 4.0 sqrt(t) kg x m^2/s, and (d) 4.0/t^2 kg x m^2/s

Aball thrown by ginger is moving upward through the air. diagram a shows a box with a downward arrow. diagram b shows a box with an upward arrow. diagram c shows a box with a downward and upward arrow equal in size. diagram d shows a box with a downward and upward arrow with the downward arrow larger in size. which force diagram represents the forces on the ball? you may neglect the effects of air resistance.
