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 \[=\frac{V}{2}dg=\frac{4\times 1000\times 9.8}{1000\times 2}=19.6N\]You need to login to perform this action.
