A 5-kg object displaces 10 kg of water. What is the force required to submerge the object?
a. 24 N
b. 147 N
c. 98 N
*d. 49 N
Buoyant Force = Weight of the Water displaced
The Attempt at a Solution
Weight of the Water displaced=10kg*9.81m/s^2=98.1N
If the buoyant force is 98.1N an equal or greater force must be applied to submerge the object.
The answer key says its 49N...why?
