Type: MCQ-numerical-Medium-Class 11
Radius of Earth is 6400 km and that of mars is 3200 km. Mass of mars is 0.1 that of Earth's mass. Then the acceleration due to gravity on mars is nearly
A
1 m/s²
B
2.5 m/s²
C
4 m/s²
D
5 m/s²
Correct Answer
Option C
Detailed Explanation
Using the formula for gravitational acceleration, g_m = g_e (M_m/M_e) (R_e/R_m)². Substituting the given values, we find g_m ≈ 4 m/s².
