Answer 1

Answer:

acc to formula

F=ma

F=5*4

=20N

Answer 2

The force required is 2 N.

Given - Weight and acceleration

Find - Force

Solution - Firstly we will calculate mass of body using the relation : W = mg, where W is weight, m is mass and g is acceleration due to gravity. Then force will be calculated using the relation F = ma, where F is force, m is mass and a is acceleration. Taking g as 10 m/s²

W = mg

Keep the values in formula

m = 5/10

Performing Division

m = 0.5 kg

F = ma

Keep the values in formula

F = 0.5*4

Performing multiplication

F = 2 N

Hence, the force required is 2 N.
