Question 20 - 2020 (06 Sep Shift 2)
When a car is at rest, its driver sees raindrops falling on it vertically. When driving the car with speed $v$, he sees that raindrops are coming at an angle 60$°$ from the horizontal. On further increasing the speed of the car to $(1 + \beta)v$, this angle changes to 45$°$. The value of $\beta$ is close to:
(1) 0.50
(2) 0.41
(3) 0.37
