The diagram shows four forces acting on a circular disc. [Figure showing a circular disc with four forces F acting] Each force has magnitude F. Two of the forces act vertically and the other two forces act horizontally. All four forces act in the same plane as the disc. No other forces act on the disc. The disc has diameter d. Which statement is correct?
AThe disc is in equilibrium because the resultant force is zero.
BThe disc is not in equilibrium because the resultant force is 4F.
CThe disc is in equilibrium because the resultant torque is zero.
DThe disc is not in equilibrium because the resultant torque is 2Fd.
