Correct Answer: Option B

Explanation

P = \(\frac{1}{v}\) and vR² = P = \(\frac{k}{v}\)......(i)

and v KR² .......(ii)

(where k is constant)

Subst. for v in equation (i) = p = \(\frac{1^2}{KR}\).....(ii)

when r = 7, p = 2

2 = \(\frac{k}{7^2}\)

k = 2 x 49

= 98

Subt. foe k in ....(iii)

P = \(\frac{98}{R^2}\)

PR² = 98
