Question

A body has a weight 50 N in air. After
immersing completely in liquid its weight
is 20 N. Then the buoyant force on the
body will be
(a) 30 N
(b) 70 N
(c) 2.5 N
(d) None of the above​

Answer 1

Answer:

hope this helps you :)

Explanation:

Actual weight of the body = 50N

and

when immeresed in water it's Boyant force + new weight = It's actual weight

Since, the new weight is 20N

Therefore,

the boyant force = 50N - 20N

Hence, the boyant force on the body will be 30N.
