= Mass of red truck = 1000 kg
= Mass of green truck= 3000 kg
= Initial Velocity of red truck = 6 m/s
= Initial Velocity of green truck
= Velocity with which they move together = 0
For elastic collision

Velocity of the green truck is 2 m/s
Answer:

Explanation:
As we know that when charge particle is projected in perpendicular magnetic field then the radius of the charge particle is given as


now we have

since here radius of proton and electron will be same
so we will have


so we have

given that



so we have
