Question

in projectile motion the radius of curvature of a point of projection is
a zero
b maximum
c minimum
d 1​

Answer 1

Answer:

i think option (B) is the correct answer

Answer 2

Answer:

The radius of curvature of a point of projection is maximum in a projectile motion. Option b is correct.

Explanation:

• When an object is thrown into the air at a particular angle, the motion is called a projectile motion.
• The curved path followed by the object is called its trajectory.

The formula of the radius of curvature at a point is :

$R=\frac{v^{2} }{g\times cos\alpha }$

where $v$ is the velocity

           $\alpha$ is the angle at which the object is thrown.

At the point of projection, the object's velocity $(v)$ is maximum. This is because the acceleration due to gravity acts on it and so, the vertical component of velocity decreases after that.

So, the radius of curvature of a point of projection is maximum in a projectile motion.

Option b is correct.
