Step-by-step explanation:
So we know that the boy weighs 60kg therefore the force that he's applying to the floor is 60g N (with g being the value attributed to the gravity in N).
The boy with the bag that he’s holding then apply a force to the ground that measures 60g + 30 N.
If there are no other forces applied , and the boy is standing still then the reaction exerted by the ground is the same as the force applied by the boy with the bag as these are two directly opposite forces.
“For every action, there is an equal and opposite reaction”
=> ||R|| = 60g + 30 N
hope it helped you!!!
Step-by-step explanation:
force applied by bag = 40N because we know that wight =force by newton law equation
I hope this helps you and plz mark me in brainlist and if it's correct then like it
