A star orbiting a black hole in a clockwise direction at a radial distance of 1.0 × 106 km is acted upon by a counterclockwise friction force of 250 N perpendicular to the orbit radius. What is the torque on the star?

upwards        

Explanation:

Torque is the vector cross product of the force and radial distance.

The direction of the torque would be perpendicular to the direction of the force and radial distance. The direction of the force is counter-clockwise. The direction of the torque would be upwards.

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary
