Question

A particle of mass m moves with constant speed along a circular path of radius r under the action of force F. Its speed is

  1. square root of F r divided by m end root  
  2. square root of F divided by r end root  
  3. square root of F blank m blank r end root  
  4. square root of F divided by m r end root  

The correct answer is: square root of F r divided by m end root


    F equals fraction numerator m v to the power of 2 end exponent over denominator r end fraction or v equals square root of fraction numerator F r over denominator m end fraction end root
