Given,
Weight on Earth’s surface = 48 N
Height from surface = (1/3) R
Total distance from Earth’s center = R + (1/3)R = (4/3)R
The gravitational force at height h is given by,
\(F = F_0 \left( \frac{R}{R + h} \right)^2\)
\(F = 48 \left( \frac{R}{\frac{4}{3}R} \right)^2 = 48 \left( \frac{3}{4} \right)^2 = 48 \times \frac{9}{16} = 27\ N\)
∴ The gravitational force at that height is 27 N.
