Answer 1

Answer:

28 N

Explanation:

According to Newton's second law of motion

The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

in another form,

Force = mass * acceleration

assuming mass is a constant since considering the same object , we can say

Force ∝ acceleration

$\frac{F_1}{F_2} =\frac{a_1}{a_2}\\ \\\frac{63}{F_2} =\frac{9}{4} \\F_2=28 N$
