A body is under the action of three forces `vecF_(1),vecF_(2) and vecF_(3)`. In which case the body cannot undergo angular acceleration ?

Options

A. `vec(F_(1)), vec(F_(2)) and vec(F_(3))` are concurrent
B. `vec(F_(1))+vec(F_(2))+vec(F_(3))=0`
C. `vec(F_(1)),vec(F_(2))` is parallel to `vec(F_(3))` but the three forces are not concurrent
D. `vec(F_(1)) and vec(F_(2))` act at the same point but `vec(F_(3))` acts at different point.

Answer

A
