1.	Two particles A and B are projected simultaneously from the top of two towers of height 10 m and 20 m respectively. Particle A is projected upwards at an angle of 45∘ with horizontal at a speed of 10√2 m/s and particle B is projected horizontally at a speed of 10 m/s towards A. What is the distance between towers if particles collide in the air ?Take g=10 m/s2.
Answer» Two particles $A$ and $B$ are projected simultaneously from the top of two towers of height $10 m$ and $20 m$ respectively. Particle $A$ is projected upwards at an angle of $45^{\circ}$ with horizontal at a speed of $10 \sqrt{2} m/s$ and particle $B$ is projected horizontally at a speed of $10 m/s$ towards $A$ . What is the distance between towers if particles collide in the air ?Take $g = 10 {m/s}^{2}$ .
