Physics-Universal Law of Gravitation
NEET Physics Universal Law of Gravitation MCQ Question
Type: MCQ-numerical-Medium-Class 11
Two particles of masses 5 kg and 10 kg are placed 3 meters apart. What is the magnitude of the gravitational force between them?
A
11 x 10^-10 N
B
22 x 10^-10 N
C
33 x 10^-10 N
D
44 x 10^-10 N
Correct Answer
Option A
Detailed Explanation
The gravitational force F between two masses m1 and m2 separated by distance r is given by F = G * (m1 * m2) / r^2. Substituting G = 6.672 x 10^-11 N m^2/kg^2, m1 = 5 kg, m2 = 10 kg, and r = 3 m, we compute F = 1.11 x 10^-10 N.
