Solution

The correct option is B False
MKS unit of pressure is $N m^{- 2}$ .
CGS unit of pressure is $d y n e c m^{- 2}$
We know that $1 N = 10^{5} d y n e$ and $1 m = 100 c m$
Thus $1 N m^{- 2} = 10^{5} d y n e \times (100)^{- 2} c m^{- 2} = 10 d y n e c m^{- 2}$
Thus CGS unit of pressure is 10 times smaller than MKS unit of pressure.

The CGS unit of pressure is 10 times greater than the MKS unit of pressure.

The correct option is B FalseMKS unit of pressure is N m−2.CGS unit of pressure is dyne cm−2We know that 1 N=105 dyne and 1 m=100 cmThus 1 N m−2=105 dyne×(100)−2 cm−2=10 dyne cm−2Thus CGS unit of pressure is 10 times smaller than MKS unit of pressure.
