Answer:

35

Step-by-step explanation:

9Kg =63N

5Kg=X (Cross Multiple)

=X×9 =5×63

divide both sides by 9

X=5×63

---------

9

=35

Answer:

35 N

Step-by-step explanation:

let w = weight of object

and m = mass of object

w = mk   where k is the constant of proportion

63 = 9k

k = 7

So, w = 7m

w = 7(5) = 35 N
