Answer: The weight of object A is 637 N
Step-by-step explanation:
Weight is defined as the force exerted by the body on any surface. It is also defined as the product of mass of the body multiplied by the acceleration due to gravity.
Mathematically,

where,
W = weight of the object A
m = mass of the object A = 65 kg
g = acceleration due to gravity on Earth =

Putting values in above equation, we get:

Hence, the weight of object A is 637 N
