If a rigid body is subjected to two forces vec F1 = 2 vec i + 3 vec j + 4 vec k acting at (3, 3, 4) and vec F2 = - 2 vec i - 3 vec i - 4 vec k acting at (1, 0, 0) then which of the following is (are) true?
A. The body maybe in equilibrium.
B. The body is under the influence of a torque only.
C. The body is under the influence of a single force.
D. The body is under the influence of a force together with a torque
