Solution
Given: Distance (r) = 1 m, mass (m1) = 75 kg, mass (m2) = 80 kg, gravitational constant (G) = 6.67 × 10-11 Nm2/kg2
To find: Gravitational force (F)
Formula: F = `("Gm"_1"m"_2)/"r"^2`
Calculation: From formula,
F = `(6.67 xx 10^-11 xx 75 xx 80)/1^2`
∴ F = 4.002 × 10-7 N
The gravitational force between Mahendra and Virat is 4.002 × 10-7 N.
