Question

A body having a mass of 0.5 kg slips along the wall of a semispherical smooth surface of radius 20 cm shown in figure. What is the velocity of body at the bottom of the surface? open parentheses G equals fraction numerator 10 text end text m over denominator s to the power of 2 end exponent end fraction close parentheses

  1. square root of 2 text end text m divided by s    
  2. 2 text end text m divided by s    
  3. 2 square root of 2 text end text m divided by s    
  4. 4 text end text m divided by s    

The correct answer is: 2 text end text m divided by s
