Question

A force of 10 N is acting on a block towards the left, if the force of 15 N is

acting towards the right. How much net force is acting on the object?A force of 10 N is acting on a block towards the left, if the force of 15 N is

acting towards the right. How much net force is acting on the object ?
(a) 5N towards left
(b) 5 N towards right
(c) 25N towards left
(d) 25 N towards right​

Answer 1

Answer:

b) 5N towards right

Explanation:

Net force = 15N-10N = 5N

And also the force is greater towards right so 5N towards right

Answer 2

Given:

A force of 10 N is acting on a block towards the left, if the force of 15 N is acting towards the right.

To find:

Net force acting in the object.

Calculation:

Considering right to be positive x axis and left to be negative x axis:

$\rm{F1 = 10 \: ( - \hat{i}) \: \: \: \: \: ......(towards \: left)}$

Again ,

$\rm{F2= 15 \: ( \hat{i}) \: \: \: \: \: ......(towards \: right)}$

Now , net force :

$\vec{F}_{net} = \vec{F1} + \vec{ F2}$

$= > \vec{F}_{net} = 10( - \hat{i}) + 15( \hat{i})$

$= > \vec{F}_{net} = - 10( \hat{i}) + 15( \hat{i})$

$= > \vec{F}_{net} = 5( \hat{i})$

So, the net force will be 5 Newton towards right.
