Question

A body is released from the top of a smooth inclined plane of inclination theta . It reaches the bottom with velocity V. If the angle of inclination is doubled for the same length of the plane, what will be the velocity of the body on reaching the ground?

  1. 2V    
  2. V    
  3. left parenthesis 2 c o s invisible function application theta right parenthesis to the power of 1 divided by 2 end exponent V    
  4. left parenthesis 2 s i n invisible function application theta right parenthesis to the power of 1 divided by 2 end exponent V    

The correct answer is: left parenthesis 2 c o s invisible function application theta right parenthesis to the power of 1 divided by 2 end exponent V
