Question

Check the correctness of the relation V=T/M,where T is the tension in the string ,v is velocity and mass is mass per unit length

Answer 1

Answer:

Dimensionally incorrect.

Explanation:

For the relation to be dimensionally correct,

[v]=[t]/[m]

[v]=LT^-1

[t]=MLT^-2

[m]=ML^-1

since LHS is not equal to RHS , hence the given relation is dimensionally incorrect.
