Assertion: In the relation`f = (1)/(2l) sqrt((T)/(m))`, where symbols have standard meaning , m represent linear mass density.
Reason: The frequency has the dimensions linear of time.

A

If both assertion and reason are ture and reason is the correct explanation of assertion

B

If both assertion and reason are true but reason is not the correct explanation of assertion

C

If assertion is true but reason is false

D

If both assertion and reson are false.

Text Solution

Verified by Experts

The correct Answer is:
B
From `f= (1)/(2l) sqrt((T)/(mu)) , f^(2) = (T)/(4l^(2) mu)`
or `mu = (T)/(4l^(2) f^(2)) = ([MLT^(-2)])/(L^(2) T^(-2)) = (M)/(L)`
`= ("Mass")/("length") `= linear mass density .
