    A body of mass 2kg is floating in water with half its volume submerge What would be the force required to wholly submerge it into the water:

    A) 2N                   

    B) 9.8N    

    C) 19.6N               

    D) 4.9N

    Correct Answer: C

    Solution :

    [c] \[U=Vpg\,(submerged)\] \[Upthrust\,\,(U)\,=\frac{V}{2}\times {{10}^{3}}\times 10\] \[V=\frac{4}{1000}{{m}^{2}}\] \[\therefore \,\]Force required to wholly sub merge the body into water \[=\frac{V}{2}dg=\frac{4\times 1000\times 9.8}{1000\times 2}=19.6N\]
