1.	In our solar system, asteriods, small satellites, comets with diameters less than 600 km can be very irregular in shape, where as those with larger diameters are spherical. Only if the rocks have sufficient strength to resists gravity then an object can maintain a non-spherical shape. In solar system, there is a planatary object of uniform density rho and radius R. Find the compressive stress S (defined as force per unit cross-sectional area ) near the centre of the planetary object
Answer» `S = piGrho^(2)R^(2)` `S = (2)/(3)piGrho^(2)R^(2)` `S = (1)/(3)piGrho^(2)R^(2)` `S = (4)/(3)Grho^(2)R^(2)` ANSWER :B
