Question

1. An object of 5 kg is acted upon by two forces, 70 N each in opposite
directions. What is its acceleration?​

Answer 1

F = m × a

where F the force ,m is the mass and a is the acceleration.

Given,

F = 70 N

m = 5 kg

substituting the value

70 N = 5kg × a

70÷5 = 14 m/s^2

Answer 2

Answer:

The above answer given by the person is totally wrong.

Explanation:

Try to Understand : It is given that ,there are two forces of 70N acting in same object but in opposite direction.

Before we continue the answer, the term given below will be helpful for in order to complete the answer.

Balanced Force : When two forces of equal magnitude in opposite direction applied on the same object. The Net Force will be zero. And There will be no change in the postion of the object.Because the two forces will cancel each other.

Now , coming back to the answer .

We get to know that what is Balanced Force , so the acceleration of the object in which two forces of 70N are applied in opposite direction will be zero.Since , there is no change in the position of the body, there is also a zero velocity in the object , and the acceleration is dependent on velocity. Therefore , the acceleration will be 0.

Thank You.
