Please explain all aspects of the question, no idea what it's asking
the question is asking the dimension of b.
In Cos[b*W/V] , b*W/V will be dimensionless because it's equal to angle. and angle has no dimension
b*W/V should be dimensionless.
given
W=[ML2T−2]
V= [LT−1]
b*W/V = b* [ML2T−2]/[LT−1] = dimentionless
b*W/V = b* [MLT−1 ] = dimentioless (! have been taken cause 1 have no dimention )
so b= 1/ [MLT−1 ]
b=T/[ML]
First option is correct.
