Answer
The torque is 60 Nm.
Step-by-step explanation
The torque of a system whose force is 30 N and the length is 2 m, then the torque is 60 Nm. The formula for torque is ( Force ) x ( moment arm ). Hence by putting values in the formula, torque = ( 30 N ) ( 2 m) which is equal to 60 Nm. The unit for torque is newton-meter (Nm). Torque is the turning effect or the force which tends to move the object in a circle and tends to rotate around a circle. Torque is a vector quantity.
The SI base units for torque is kg ⋅ m 2 ⋅ s − 2.
