138373 If the density of a small planet is the same as that of earth, while the radius of the planet is 0.2 times that the earth, the gravitational acceleration on the surface on that planet is

1 0.2 g
2 0.4 g
3 2 g
4 4 g
Gravitation

138374 A fighter plane, flying horizontally with a speed 360 km/h at an altitude of 500 m drops a bomb for a target straight ahead of it on the ground. The bomb should be dropped at what approximate distance ahead of the target? Assume that acceleration due to gravity (g) is 10 ms2. Also neglect air drag.

138375 Two point objects of masses 1.5 g and 2.5 g respectively are at a distance of 16 cm apart, the centre of gravity is at a distance x from the object of mass 1.5gm where x is

Gravitation

138372 Two masses m1 and m2(m1<m2) are released from rest from a finite distance. They start under their mutual gravitational attraction-

1 Acceleration of m1 is more than that of m2.
2 Acceleration of m2 is more than that of m1.
3 Centre of mass of system will remain at rest in all the reference frame
4 Total energy of system does not remain constant.
