At which of the following place, the weight of an object is maximum?
At poles
Weight \(W = mg\), so for a fixed mass it is greatest where \(g\) is greatest. The Earth is an oblate spheroid — flattened at the poles and bulging at the equator — so the polar radius is smaller, making \(g \propto 1/r^2\) larger at the poles. Additionally, Earth's rotation produces a centrifugal effect that reduces apparent \(g\) at the equator but is zero at the poles. Both effects combine to make \(g\), and therefore weight, maximum at the poles (≈9.832 m/s²) and minimum at the equator (≈9.780 m/s²).
When did Henry Cavendish report the measurement of the gravitational constant with the mass and density of the Earth?
If speed of rotation of the earth increases, the weight of the body?
Who among the following is credited with postulating three laws of planetary motion?
Who among the following was the first to conclude that in vacuum all objects fall with the same acceleration g and reach the ground at the same time?
Which of the following statement is correct?
I. Gravitation is a weak force unless large masses are involved.
II. The weight is equal to the product of mass and acceleration due to gravity.
What is the reason that the value of g (acceleration due to gravity) becomes greater at the poles than at the equator?
If the acceleration due to gravity on the surface of earth is g, then the acceleration due to gravity on the surface of a planet whose mass is same as that of earth and radius is twice as that of earth is ___________.
A man's mass is 72 kg on the earth. His mass on the moon will be:
