Question

36. The reading of spring balance, as shown in the
figures is


(1) 60 kgf
(3) 20 kgf
(2)30 kgf
(4) 50 kgf​

Answer 1

Answer:

The answer to this is no 1 i.e 60 kgf because 30 kgf of force is applied from both of the same sides but the f is missing in this diagram only kg is there and and you have given kgf in the options.

Answer 2

(2) 30kgf

Explanation:

Reading of the spring balance= Tension in the string

And tension in the string = mg

= 30kgf or 300 N

Therefore reading in the spring balance is 30kgf (where kgf means kilogram force)
