Question

pls provide proper explanation for the above question in the attachment​

Answer 1

Answer:

(4)

Explanation:

We have

$v= R_h(\frac{1}{n^2}- \frac{1}{64})\\</p><p>v=\frac{R_h}{n^2}- \frac{R_h}{64}\\</p><p>\text{Thus it will be a line with slope} R_h \\</p><p>(\text{By comparing with y=mx+c})$
