The potential energy of a body of mass m is given by U = px + qy + rz.

1.	The potential energy of a body of mass m is given by U = px + qy + rz. The magnitude of acceleration of the body will be
Answer» `(p + q + R)/(m)` `sqrt((p^(2) + q^(2) + r^(2))/(m))` `sqrt((p^(3) + q^(3) + r^(3))/(m))` `sqrt((p^(4) + q^(4) +r^(4))/(m))` Answer :B
