9. A body moves with uniform velocity when the resultant force on it is A.

  • A. greater than the frictional force acting on it.
  • B. less than the frictional force acting on it.
  • C. equal to zero.Correct
  • D. equal to the frictional force acting on it.

Explanation

When a body moves with uniform velocity, it means there is no acceleration (the acceleration is zero). Since F=ma, if a=0, then F=0. Thus, for a body to move at uniform velocity, the net/resultant force on the body must be equal to zero.
