Question

A body of mass 3 kg is floating in water, half its volume submerged. The force required to wholly submerge it into water is

Answer 1

15 N since half volume is submerged we can say 1.5 Kg is submerged hence bouyant force is acting upwards and to fully sink the bouyant force needs to be overcomed.

Answer 2

Answer:

Explanation:since volume is half inside so volume displaced will be 0.5cc.

Then required force= 0.5×10/0.5×9.8=98N
