Question

When an object is shot from the bottom of a long smooth inclined plane kept at an angle $60 \degree$with horizontal, it can travel a distance $x_1$ along the plane. But when the inclination is decreased to $30 \degree$ and the same object is shot with the same velocity, it can travel $x_2$ distance. Then $x_1:x_2$ will be:

• A. $1:\sqrt2$
• B. $\sqrt2:1$
• C. $1:\sqrt3$
• D. $1:2\sqrt3$

Answer 1

Answer: (C)

$1:\sqrt3$

Answer 2

The correct option is (C) :$1:\sqrt3$
