359589 If mass of the earth were doubled, to keep the acceleration due to gravity constant on the earth, its radius

1 Must be made \(\sqrt{2}\) times initial radius
2 Should remain constant
3 Must be halved
4 Must be be quadrupled

359590 The maximum vertical distance through which a fully dressed astronaut can jump on the earth is 0.5\(m\). If mean density of the moon is two thirds that of the earth the radius is one quarter that of the earth, the maximum vertical distance through which he can jump on the moon and the ratio of time duration of jump on the moon to that on the earth are:

1 \(3\;m,6:1\)
2 \(6\;m,3:1\)
3 \(3\;m,1:6\)
4 \(6\;m,1:6\)

359591 The mass and diameter of a planet have twice the value of the corresponding parameters of earth. Acceleration due to gravity on the surface of the planet is

1 \(9.8\;m/{s^2}\)
2 \(19.6\;m/{s^2}\)
3 \(980\;m/{s^2}\)
4 \(4.9\;m/{s^2}\)
PHXI08:GRAVITATION

359592 If a planet consists of a satellite whose mass and radius were both half that of the earth. The acceleration due to gravity at its surface would be (\(g\) on earth \(\left. { = 9.8\;m/{{\sec }^2}} \right)\)

1 \(19.6\;m/{\sec ^2}\)
2 \(29.4\;m/{\sec ^2}\)
3 \(4.9\;m/{\sec ^2}\)
4 \(8.9\;m/{\sec ^2}\)
