Question

The effective acceleration of a body, when thrown upwards with acceleration a will be:

  1. square root of a minus g to the power of 2 end exponent end root  
  2. square root of a to the power of 2 end exponent plus g to the power of 2 end exponent end root  
  3. left parenthesis a minus g right parenthesis  
  4. left parenthesis a plus g right parenthesis  

The correct answer is: left parenthesis a minus g right parenthesis


    Net acceleration of a body when thrown upward equals acceleration of body – acceleration due to gravity equals a minus g
