Question

A beaker filled with liquid, is placed in the pan of a spring balance. If you dip your finger in it, the reading of the balance will be ?

• A. increased
• B. unchanged
• C. decreased
• D. may increase or decrease according to the nature of liquid

Answer 1

The correct option is A increased

$\begin{array}{c}\text{If we dip our finger in the beaker filled with}\\ \text{liquid the liquid with exert an upward buoyant}\\ \text{force to our finger.}\\ \text{And by newton's Law every action generates equal}\\ \text{and opposite reaction and hence the finger}\\ \text{will also exert the force on the liquid.}\\ \text{- And thus the reading of the Balance will increase.}\end{array}$
