Explanation / Answer

Here ,

a) acceleration due to gravity = G * M/R^2

acceleration due to gravity = 6.673 *10^-11 * 1.99 *10^30/(6.96 *10^8)^2

acceleration due to gravity = 274.1 m/s^2

the acceleration due to gravity is 274.1 m/s^2

b)increase in weight = 274.1/9.81

increase in weight = 28 times
