In an immersion measurement of an odd-shaped metal object, the weight of the object is found to be 980 N when submerged in water. When it is submerged in a heavier Bromine liquid (density 3100 kg/m3), the object weighs 840 N. What is the volume of this object

Explanation:

Given

The weight of the object, when submerged in the water is

When it is submerged in the bromine liquid, it weighs

Suppose,

for water,

For bromine

Divide (i) and (ii)

Put the density value in equation (i)

i think the answer would be b

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
