Question

Calculate the net force of the following situation. ←10 Newtons + →30 Newtons

Question 1 options:

←40 Newtons


←20 Newtons


→40 Newtons


→20 Newtons

Answer 1

The net force will be 20 N.

Step-by-step explanation:

Given data:

F = 30 N

F = 10 N

ΣF = ?

Solution:

Formula:

ΣF = + F - F

ΣF = 30 N - 10 N

ΣF = 20 N

The net force will be 20 N.

Answer 2

→20 Newtons

Step-by-step explanation:

These are two vectors are in opposite directions. Let's say;

`V_(1)` = 10 N

`V_(2)` = 30N

But
`V_(2)` moves in the positive direction (given in the question) as against tht of
`V_(1)`, so:

`V_(1)` = - 10 N

`V_(2)` = + 30N

The net force =
`V_(1)` +
`V_(2)`

= -10 + 30

= + 20N

This shows that the net force is in the direction of force
`V_(2)` .

Thus, net force is →20 Newtons
