SURFACE OF MOON

Assertion On the surface of moon, value of g is (1)/(6)th the value on the surface of earth. A particle is projected as projectile under similar condition on the surface of moon and on the surface of earth. Then values of T,H and R on the surface of moon will become six times. Reason T, H and R prop (1)/(g)

Assertion : On earth's satellite, we feel weightlessness. Moon is also satellite of earth. But on the surface on moon, we do not feel weightlessness Reason : Gravitational force by earth on us on the surface of moon is zero. But gravitational force by moon on us on its surface is non-zero.

Assertion : Water kept in an open vessel will quickly evaporate on the surface of the moon. Reason : The temperature at the surface of the moon is much higher than boiling point of the water.

If the mass of body is M on the surface of the earth ,then its mass on the surface of the moon will be

A closed bottle containing water at 30^(@)C is open on the surface of the moon. Then -

Similar balls are thrown vertically each with a velocity 20ms^(-1) , one on the surface of earth and the other on the surface of moon. What will be ratio of the maximum heights attained by them? (Acceleration on moon = 1.7 ms^(-2) approx)

There is crater of depth R//100 on the surface of the moon (raduis R ). A projectile is fired vertically upwards from the crater with a velocity, which is equal to the escape velocity v from the surface of the moon. The maximum height attained by the projectile, is :
