At poles
At equator
At $45^°$ latitude
At $40^°$ latitude
(b)Weight is least at the equator.
If the radius of the earth shrinks by $1.5\%$ (mass remaining same), then the value of acceleration due to gravity changes by ……. $\%$.
A body weight $500 \,N$ on the surface of the earth. How much would it weigh half way below the surface of the earth ……. $N$
Derive the equation for variation of $g$ due to height from the surface of earth.
A planet has same density as that of earth and universal gravitational constant $G$ is twice that of earth, the ratio of acceleration due to gravity, is.
Given below are two statements: one is labelled as Assertion $A$ and the other is labelled as Reason $R$.
Assertion $A:$ A pendulum clock when taken to Mount Everest becomes fast.
Reason $R:$ The value of $g$ (acceleration due to gravity) is less at Mount Everest than its value on the surface of earth.
In the light of the above statements, choose the most appropriate answer from the options given below
