Question

When two equal forces act on the same point of an object but in opposite directions, ____________

• A. net force on the body is zero but not net torque.
• B. the velocity of the body increases.
• C. net torque is zero but not net force.
• D. both net force and net torque are zero.

Answer 1

The correct option is D both net force and net torque are zero.

The resultant of two equal forces acting in opposite directions is zero. Also, since they are acting at the same point, they result in equal and opposite torques and thus net torque will be zero.
