If unit of mass become `2` times the unit of length becomes `4` time and the unit of time in the unit of Plank's Due to the unit of plank's constant because n time The value of n is

Options

A. `3`
B. `5`
C. `6`
D. `8`

Answer

d

Explanation

The unit of plank's constant is joule second or `kgm^(2)` per second
`(("unit of mass")("unit of length")^(2))/(("unit of time")) = (2 xx 4^(2))/(4) = 8 "times"`
`:. n = 8`
