A) \[J\,{{s}^{-2}}\]
B) \[J\,{{s}^{2}}\]
C) \[J\,s\]
D) \[J/s\]
Correct Answer: C
Solution :
The formula for Plancks constant is \[=\frac{Energy}{Frequency}\] Hence, unit of Plancks constant is \[=\frac{Unit\text{ }of\text{ }energy}{Unit\text{ }of\text{ }frequency}=\frac{joule}{{{\sec }^{-1}}}\] \[=J\,s\]
