Question

A steel rod has a volume 2 times more than rod b the mass is blank that of rod b what comes I the blank?

Answer 1

Answer:

Volune of Steel Rod A is 2V ,if of B is V...

mass=volume×density

M=V.D

Since both are steel rods , they have same density.

For A- For B-

Let Mass be M Let mass be M'

M=2V.D M'=V.D

M/2=V.D and M'=V.D

Hence , M/2=M'

So , M=M'×2

So , Mass of Rod B is 'half of Mass of A . -
