The spring balance A reads 2 kg with a block of mass m suspended from it. A balance B reads 5 kg when a beaker with liquid is put on the pan of the balance. The two balances are now so arranged that the hanging mass is inside the liquid in a beaker as shown in the figure.

The effective weight of the block in the liquid will become less than

2 k g

due to buoyancy of liquid. As a result of which

A

will read less than

2 k g

.
As the body immersed in liquid has some effective weight acting downwards so the reading of

B

will be more than

5 k g

.

Q. The spring balance $A$ reads $2 k g$ with a block of mass $m$ suspended from it. A balance $B$ reads $5 k g$ when a beaker with liquid is put on the pan of the balance. The two balances are now so arranged that the hanging mass is inside the liquid in a beaker as shown in the figure.

The balance $A$ will read more than $2 k g$

The balance $B$ will read less than $5 k g$

The balance $A$ will read less than $2 k g$ and $B$ will read more than $5 k g$

The balance $A$ will read more than $2 k g$ and $B$ will read less than $5 k g$

The effective weight of the block in the liquid will become less than $2 k g$ due to buoyancy of liquid. As a result of which $A$ will read less than $2 k g$ .
As the body immersed in liquid has some effective weight acting downwards so the reading of $B$ will be more than $5 k g$ .

The balance A will read more than 2kg

The balance B will read less than 5kg

The balance A will read less than 2kg and B will read more than 5kg

The balance A will read more than 2kg and B will read less than 5kg
