What is the resultant force?
8 NA
14 N
3N
3N
22 N

option will be ''B'' 0N

Explanation:

There are two forces acting upward 8N and 14N which is equal to 22N(upward force)

since, 22N is also acting downwards

both the forces will cancel each other and the the outcome will be zero.

Now, there is a 3N force acting on the left and right. So, they too, will cancel each other and the result will be zero.

In simple words, the box won't move in any direction Since it's being pulled with equal strength from all sides.

hope this helps

i am single too don't feel bad

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.
