Question

Two small balls having the same mass and charge and located on the same vertical at heights h₁ and h₂ are thrown in the same direction along the horizontal at the same velocity v. The first ball touches the ground at a distance l from the initial vertical. At what height H₂ will the second ball be at this instant ? The air drag and the effect of the charges induced on the ground should be neglected.

Options

• `"h"_1 + "h"_2 - "g"(l/"v")^2`

• `"h"_1 - "h"_2 - "g"(l/"v")^2`

• `"h"_1 + "h"_2 - "g"(l/"v")^(1//2)`

• `("h"_1 + "h"_2)/2 - "g" (l/"v")^2`

Answer 1

`"h"_1 + "h"_2 - "g"(l/"v")^2`
