The acceleration due to gravity on the surface of moon is 1.67m/s2
• If the radius of moon is
1.74 x 106 m, calculate the mass of the moon. Use the known value of G.

A spherical mass of 20kg lying on the surface of earth is attracted by another spherical mass of
150Kg with a force equal to 0.25mg wt. The centers oftwo masses are 30cm apart. Calculate
the mass of earth. [Given: Radius of earth = 6 x 108 em]

Calculate the force of attraction between two bodies each of mass lOOKg and 1m apart on the
surface of earth. Will the force of attraction be different if the same bodies are taken on the
moon, their separation remaining constant? Given: G = 6.67 x 10-11 N-m2/kg2

A sphere of mass 40Kg is attracted by another sphere of mass 15Kg with a force of 1/10 mg
wt. Find the value of constant of gravitation if centers of spheres are 20cm apart.
[Given I kg wt = 9.8 N]

If the radius of earth were increased by a factor of 3, by what factor would its density have to
be changed to keep 'g' same?

A sphere of mass 40Kg is attracted by another sphere of mass 15Kg with a force of 1/10 mg
wt. Find the value of constant of gravitation if centers of spheres are 20cm apart.
[Given I kg wt = 9.8 N]

What are the similarities between (nn) and (pp) forces?

Experimentally the study of p-p scattering is capable of much higher accuracy than n-p scattering ,why?

calculate the average energy per revolution and find energy by electron in a betatron to which is applied a maximum magnetic field of 0.5 tesla operating in a stable orbit of diameter?
