Atorque acting on an object tends to produce a. equilibrium b. rotation c. linear motion d. velocity e. a center of gravity

B. rotation

The torque is defined as the twisting or turning effort applied by a force. Recall that a force when acting on a body tends to produce a translational motion, but the rotational, on the other hand, is performed by the torque. When the torque acts on a body it determines an angular acceleration. Torque is important in many subjects in physics like electrical motor, gyroscopes, among others. Finally, the torque vector is defined as:

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
