Physics And Measurement Question 333
Question: The unit of potential energy is
[AFMC 1991]
Options:
A) $ g(cm/{{\sec }^{2}}) $
B) $ g{{(cm/\sec )}^{2}} $
C) $ g(cm^{2}/\sec ) $
D) $ g(cm/\sec ) $
Show Answer
Answer:
Correct Answer: B
Solution:
Potential energy $ =mgh=g( \frac{cm}{{{\sec }^{2}}} )cm=g{{( \frac{cm}{\sec } )}^{2}} $
