Question

The physical quantity which has dimensional formula as that of `("energy")/("mass"xx"length")` is
A. Force
B. Power
C. Pressure
D. acceleration

Answer 1

Correct Answer - d
`|("Energy")/("Mass "xx" Length")|=[("Force "xx" Displacement")/("Mass "xx" Length")]`
`=[(M^(1)L^(1)T^(-2)xxL^(1))/(M^(1)xxL^(1))]=[L^(1)T^(-2)]`= [Acceleration]
The physical quantity is acceleration.
