A simple pendulum has a time period T1, when on the earth’s surface; and T2, when taken to a height R above the earth’s surface (R is the radius of the earth). The value of T2/T1 is?

A simple pendulum has a time period T1, when on the earth’s surface; and T2, when taken to a height R above the earth’s surface (R is the radius of the earth). The value of T2/T1 is? Correct Answer 1

g‘/g=(R/(R+R))2=1/4 As T∝1/√g T2/T1 = √(g/g‘)=√(4/1)=2.
