The physical quantity which isnot a unit of energy is

A

Volt-Coulomb

B

MeV-s

C

Henry`("ampere")^(2)`

D

Farad-`("volt")^(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
MeV-s is not a unit of energy, while others are unit of energy.
Volt is work per unit charge.
Coulomb is unit of charge.
So, volt-coulomb is workk with unit of energy.
MeV-s is megaelectron volt-second.
Mega is prefix (or unit less multiplier)
Electron-volt is (charge)`xx` (volt) has unit of energy but MeV-s has unit of (energy) `xx` (time) Now,
`=[(("henry")xx("ampere"))/("time")]`
`[("ampere")xx("time")]`
`=`(volt)(coulomb)`=` unit of energy
Farad `=("volt")^(2)`
`=[("farad")("volt")("volt")]`
`=("charge")("volt")=` unit of energy
