Question

1. A force F is applied on the spring balance as shown in the figure given below. The reading of A and B respectively will be
​

Answer 1

Answer:

the same amount of force will be applied on a and b

Answer 2

Answer:

The reading of A and B respectively will be the same =$\frac{F}{2K}$.

Explanation:

As the two springs are in series:$F=Kx +Kx$

Extensions on both the spring will be the same, as both the spring have the same spring constant and are in series.

Therefore, $F=Kx +Kx$

$\implies F=2Kx$

$\implies x=\frac{F}{2K}$
