Question on: JAMB Mathematics - 2006
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
Ask EduPadi AI for a detailed answer
Correct Option: B
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/2π = √1/g
(T/2π)2 = (√1/g)2
T2/4π2 = 1/g
T2 x g = 4π2 x l
G = (4π2 x l) / T2
