An object can be completely immersed in a liquid when:
- The upward and downward forces are balanced.
- The downward force is more than the upward force.
- Both A and B
- None of the above
Correct Answer: Option(c)
Solution: an object immersed in fluid have two forces acting on it i.e mg and buoyant force , now if mg is greater than buoyant force than body would sink and hence get completely immersed . and in case bouyant force completely balances mg than body would float but will be completely immersed inside the liquid.
hence option (C) would be correct.
