359628 Assertion :
At pole value of acceleration due to gravity \(g\) is greater than that of equator.
Reason :
Earth rotates on its axis in addition to revolving round the sun.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.

359629 If the speed of rotation of earth about its axis increases, then the weight of the body at the equator will

1 Increase
2 Decrease
3 Remains unchanged
4 Sometimes decrease and sometimes increase
PHXI08:GRAVITATION

359630 The imaginary angular velocity of the earth for which the effective acceleration due to gravity at the equator shall be zero is equal to (take, \(g=10 \mathrm{~ms}^{-2}\) for the acceleration due to gravity, if the earth were at rest and radius of earth equal to \(6400 \mathrm{~km}\).)

2 \(2.50 \times {10^{ - 3}}\,rad\,{s^{ - 1}}\)
3 \(3.75 \times {10^{ - 3}}\,rad\,{s^{ - 1}}\)
4 \(5.0 \times {10^{ - 3}}\,rad\,{s^{ - 1}}\)

359631 The acceleration due to gravity on the earth's surface at the poles is \(g\) and angular velocity of the earth about the axis passing through the pole is \(\omega\). An object is weighed at the equator and at a height \(h\) above the poles by using a spring balance. If the weights are found to be same, then \(h\) is : (\(h < < R\), where \(R\) is the radius of the earth)

1 \(\dfrac{R^{2} \omega^{2}}{2 g}\)
2 \(\dfrac{R^{2} \omega^{2}}{g}\)
3 \(\dfrac{R^{2} \omega^{2}}{4 g}\)
4 \(\dfrac{R^{2} \omega^{2}}{8 g}\)
