Question

1 meter long massless string fixed with a wall is pulled horizontally by applying force of magnitude 10N calculate tension at point .5m away from wall

Answer 1

For massless string, tension is same at all points

as force applied on both sides in 10 Newtons,
Tension=10 Newtons

Answer 2

Answer:

The tension will be 10 N.

Explanation:

Given that,

Length of string = 1 m

Force f = 10 N

We need to calculate the tension at point 5 m away from wall

According to newton's third law,

When one object apply a force on another object then the another object apply equal and opposite force on a first object.

So, The tension will be same at all points on the string.

The string is pulled by the 10 N force then the tension at the point 5 m away from the wall will be 10 N.

Hence, The tension will be 10 N.
