If T = 2 π √1/g, make g the subject of the formula

A.

(4π l2) / T

B.

(4π2l) / T2

C.

(4π2l2) / T2

D.

(2π√l) / T

Correct Answer: (4π2l) / T2

Explanation

T = 2 π √1/g T/2π = √1/g (T/2π)2 = (√1/g)2 T2/4π2 = 1/g T2 x g = 4π2 x l G = (4π2 x l) / T2

T = 2 π √1/g T/2π = √1/g (T/2π)2 = (√1/g)2 T2/4π2 = 1/g T2 x g = 4π2 x l G = (4π2 x l) / T2
