A body is projected vertically upwards with a velocity of $20 \mathrm{~m} \mathrm{~s}^{-1}$. If the potential energy of the body at a height of 5 m from the ground is 100 J, then the kinetic energy of the body at a height of 10 m from the ground is (Acceleration due to gravity $=10 \mathrm{~m} \mathrm{~s}^{-2}$ )

• Correct answer
  A

  200 J
• B

  300 J
• C

  150 J
• D

  250 J

Hence, the correct answer is option: 'A'.
