MCQ
Two small balls having the same mass and charge and located on the same vertical at heights $h_1$ and $h_2$ are thrown in the same direction along the horizontal at the same velocity $v$ . The first ball touches the ground at a distance $I$ from the initial vertical. At what height $H _2$ will the second ball be at this instant ? The air drag and the effect of the charges induced on the ground should be neglected.
- ✓$\text{h}_1+\text{h}_2-\text{g}\Big(\frac{\ell}{\text{V}}\Big)^2$
- B$\text{h}_1-\text{h}_2-\text{g}\Big(\frac{\ell}{\text{V}}\Big)^2$
- C$\text{h}_1+\text{h}_2-\text{g}\Big(\frac{\ell}{\text{V}}\Big)^\frac{1}{2}$
- D$\frac{\text{h}_1+\text{h}_2}{-\text{g}}-\text{g}\Big(\frac{\ell}{\text{V}}\Big)^2$
