Answer:
Weight of body = 490 Newton
Explanation:
Mass of the body is the total amount of matter contained in the body but Weight of the body is the force exerted by gravity on the body. Weight of the body depends upon acceleration due to gravity of the planet.
Thus,
Weight = mass × acceleration due to gravity
W = mg
W = weight of the body
m = mass of the body
g = acceleration due to gravity
W = 50 × 9.8
W = 490 
W = 490 Newton
Hence, weight of the body is 490 Newton.
Answer:
because it has gravity in it . as it has more mass which can attract the things like we human are also attracted towards its centre and also mass is directly proportional to gravity which leads it to be round in shape.
