Vishal and Vikas are playing with two different balls of masses m and 2m respectively. If Vishal throws his ball vertically up and Vikas at an angle 0, both of them stay in our view for the same period. The height attained by the two ball are in the ratio :

Options

A. `2:1`
B. `1:2`
C. `1:1`
D. `1:3`

Explanation

To solve the problem, we need to analyze the motion of both balls thrown by Vishal and Vikas.

### Step-by-Step Solution:

1. **Understanding the Problem**:
- Vishal throws a ball vertically upwards with an initial velocity \( u_1 \).
- Vikas throws a ball at an angle \( \theta \) with an initial velocity \( u_2 \).
- Both balls are in view for the same time period \( t \).
