Answer :
Final answer:
The force required to lift a 20 kg body is 196 N.
Explanation:
To lift a 20 kg body, you need to apply a force equal to its weight. The weight of an object can be calculated using the formula: weight = mass x acceleration due to gravity. On Earth, the acceleration due to gravity is approximately 9.8 m/s². So, the force required to lift the 20 kg body would be:
Force = mass x acceleration due to gravity
= 20 kg x 9.8 m/s²
= 196 N
Therefore, the correct answer is option b) 196 N.
