A body is projected horizontally with a velocity u from a point which is at a height h above the ground level. The range (R) is (Take acceleration due to gravity = g units)
1
\(R = h \sqrt \frac {2u}{g}\)
2
\(R = u \sqrt \frac {2g}{h}\)
3
\(R = g \sqrt \frac {2h}{u}\)
4
\(R = u \sqrt \frac {2h}{g}\)
