Question

A force of 2 kg is applied at one end of a spring
balance kept horizontally and an equal force of
2 kg is applied at the other end in the opposite
direction, simultaneously. Then the reading on
the spring balance is:​

Answer 1

Answer:

The reasong on the spring balance will be zero.

That is because

As you are applying equal forces from both the end of the spring. The net force Generating is Zero.

In pure physics way-

Force is a vector quantity.

In this case the both vectors are antiparallel

The their resultant Vector will be-

A(vector)-B(vector)=R(resultant)

As both the vectors are same so

A-A=R

0=R

The the resultant will be zero.

Answer 2

Answer: Zero.

Explanation:

• Spring balance is an instrument which is used to measure weight of  an object.
• It works on the principle that by how much force the earth pulls the object.
• If we apply equal forces at both the ends then the net force on the spring balance is zero and the reading will be zero.
• Hence, the reading on spring balance will be zero.
