Given that p varies as the square of q and q varies inversely as the square root of r. How does p vary with r?
p varies as the square of r
p varies as the square root of r
p varies inversely as the square of r
p varies inversely as r
Correct answer is D
p∝q2
q∝1√r
p=kq2
q=c√r
where c and k are constants.
q2=c2r
p=kc2r
If k and c are constants, then kc2 is also a constant, say z.
p=zr
p varies inversely as r.
