6.5 x 9.8
=63.7
so the answer is 64N

Answer:

F = 64 N

Explanation:

When 1 kg of weight attached with the spring, the scale reads 9.8 N. Weight of an object is the product of mass and acceleration due to gravity. Let F is the force exerted by gravity on 6.5 kg. It can be calculated as :

$F=mg$

$F=6.5\ kg\times 9.8\ m/s^2$

F = 63.7 N

or

F = 64 N

So, the force exerted by gravity on 6.5 kg is 64 N.
