The physical quantity which isnot a unit of energy is

Options

A. Volt-Coulomb
B. MeV-s
C. Henry`("ampere")^(2)`
D. Farad-`("volt")^(2)`

Answer

B

Explanation

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
