Answer» tion:If Torque = 0 ; that means either FORCE(PERPENDICULAR) = 0 , or Radius = 0; Case I : If Force(perpendicular) = 0; that means Acceleration(perpendicular) will be EQUAL to 0; therefore Velocity(perpendicular) won't change . This implies Angular Momentum (L=mvr) won't change. Angular Momentum remains constant.Please mark this answer as BRAINLIEST
