The square root of the dimension of energy divided by mass is the same as that of:
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3, i.e. velocity.
Dimension of energy is [ML²T⁻²]. When divided by mass [M], it becomes [L²T⁻²]. Taking the square root gives [LT⁻¹], which is the dimension of velocity.
