Compare the force of gravity of the mass on the surface of the earth with the same mass if it was moved away two (2) earth's radii from the center of the earth.
( it’s number 6 )

Explanation:

According to law of gravitational fields You have already knew about factors that are affected on gravitational force

F ∝M1 ×M2

F ∝ (1 / R² )

F gravitational force

M1 ,M2 = Masses

R = Distance between two masses

There for if we double the length between masses force will be reduced 4 times when compared with previous value

F1 ∝ (1/R²) (1)

F2 ∝(1/(2R)²) (2)

(1)/(2) F1/4 = F2

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
