MCQ
The unit of potential energy is
- A$gm\;(cm/{\sec ^2})$
- ✓$gm\;{(cm/\sec )^2}$
- C$gm\;(c{m^2}/\sec )$
- D$gm\;(cm/\sec )$
✓
Answer
Correct option: B.
$gm\;{(cm/\sec )^2}$
b
(b) Potential energy $ = mgh = g\left( {\frac{{cm}}{{{{\sec }^2}}}} \right)cm = g{\left( {\frac{{cm}}{{\sec }}} \right)^2}$
(b) Potential energy $ = mgh = g\left( {\frac{{cm}}{{{{\sec }^2}}}} \right)cm = g{\left( {\frac{{cm}}{{\sec }}} \right)^2}$
