From certain height `h` two bodies are projected horizontally each with velocity `v`.One body is projected towards North and the other body is projected towards east. Their separation on reaching the ground

Options

A. `sqrt((2v^(2)h)/g)`
B. `sqrt((4v^(2)h)/g)`
C. `sqrt((v^(2)h)/g)`
D. `sqrt((8v^(2)h)/g)`

Answer

B

Explanation

`R_(x)=vsqrt((2h)/g)hati,R_(y)=vsqrt((2h)/g)hatj,R=sqrt(R_(x)^(2)+R_(y)^(2))`
