A raindrop of mass \( 1 \mathrm{~g} \) falling from a height of \( 1 \mathrm{~km} \)
\( \mathrm{P} \)
hits the ground with a speed of \( 50 \mathrm{~m} \mathrm{~s}^{-1} \). Which of the following statements is correct?
(Take \( g=10 \mathrm{~m} \mathrm{~s}^{-2} \) )
(1) The loss of potential energy of the drop is \( 10 \mathrm{~J} \).
(2) The gain in kinetic energy of the drop is \( 1.25 \mathrm{~J} \).
(3) The gain in kinetic energy of the drop is not equal to the loss of potential energy of the drop.
(4) All of the above.
