dimensional analysis

I have been presented the formula p=v^2/R
I know the dimensions of p and v and have been asked to determine the dimensions of R
I have come to the conclusion L^-1T and am hoping someone can tell me if this is correct or not if not advise me , if you dont know this dimensions of p and v ask and I will post them. thanks

Just rearrange, so [R]=[v2][p] [R] = \frac{[v^2]}{[p]}

Note: edit.

yes I did this in my workings out but obviously it's not as easy as that ?

Tell me the dimensions of v and p.

p = MLT^2T^-3
v= L^0.5M^0.5T^-1

Answer is L^2M^2T^-3

Sounds like an A Level question but google Pi Theorem. It is a good way to solve these fast. You’ll come across it at uni if you do science or engineering.

I have the same problem. could anyone share with their workings so I can see the process to take to get the answer?
