Question

A rock weighs 33.6 N on Planet X and 49 N on Earth. What is g on Planet X?

Answer 1

6.72m/s square. So hope you like it. ✌

Answer 2

• Here force acting on the object is normal force

• normal force = mg
______________________

•Force = F = 49 N
•acceleration due to gravity = g = 9.8 m/s²
•mass = m = ?

F = mg

49N = m×9.8m/s²

49N/9.8m/s² = m

5 Kg = m
__________________________________

• so mass of the object is 5 Kg

• mass is constant quantity in everywhere means it's mass also in planet X is same

•Force = F = 33.6N
•mass = m = 5 Kg
•acceleration due to gravity = g = ?

F = mg

F/m = g

33.6N/5kg = g

6.72 m/s² = g
