A ball is projected to attain the maximum range. If the height attained is H, the range isA. HB. 2HC. 4HD. H/2

Answer» Correct Answer - C
Maximum range for a given velocity is attained at `theta=45^(@)`
`R_("max")=(u^(2)sin2theta)/(g)rArrR_("max")=(u^(2)sin90^(@))/(g)=(u^(2))/(g)`
`therefore R_("max")=4.H_("max")`
