Answer:

[B]= ML^3T^-2

Explanation:

[W] = ML^2T^-2

[C]=[X]= L

so,

According to Homogeneity Principle,

Dimension of Work is equal to dimension of B/(c-x).

so on equating both sides,

we will get [B]

Given :

The work done'W' by a body varies with displacement 'x' as :

W=Ax+\dfrac{B}{(c-x)^2}

To Find :

The dimensional formula for B .

Solution :

We know , dimensional formula of work done is :

W=[M\ L^2\ T^{-2}]

Now , by rule of dimension rule .

Dimension of \dfrac{B}{(c-x)^2} must be equal to the dimension of work .

Therefore ,

\dfrac{B}{[L]^2}=[M\ L^2\ T^{-2}]\\\\B=[M\ L^4\ T^{-2}]
