Which two of the following five physical parameters have the same dimension?
(1) Energy density
(2) refractive index
(3) dielectric constant
(4) Young's modulus
(5) magnitic field

A

C and E

B

A and D

C

A and E

D

B and D

Text Solution

Verified by Experts

The correct Answer is:
B
Energy density `=("Energy")/("Volume")=(Fl)/(l^3)`
`(F)/(l^2)=[ML^(-1)T^(-2)]`
Young.s modulus `=("stress")/("strain")= (F)/(A)=([MLT^(-2)])/([L^2])=[ML^(-1)T^(-2)]`
