As per given equation we have
now as per the dimensional analysis we can say that dimension of right side of equation must be equal to left side of the equation
now as per left side of equation its dimension is same as length or meter
now we can say it should be meter on right side also
similarly for other term we have
<em>so above are the dimensions of b and c</em>
