Assertion : For angular projection when angle of projection θ = tan^-1(1) the horizontal range is four times the maximum height. Reason : The horizontal range of projectile is directly proportional to square of velocity and inversely proportional to acceleration due to gravity. 1. In a cricket match a batswoman hits a boundary 6 times [...]

ASSERTION Generally the path of a projectile from the earth is parabolic but it is elliptical for projectiles going to a very great height. REASON Up to ordinary height the projectile moves under a uniform gravitational force, but at great heights, projectile moves under a variable force. 1. In a cricket match a batswoman hits [...]

ASSERTION A body can have acceleration even if its velocity is zero at a given instant of time. REASON A body is momentarily at rest when it reverses its direction of motion. ASSERTION A body can have acceleration even if its velocity is zero at a given instant of time. REASON A body is momentarily [...]

A cyclist is moving on a circular track of radius 80 m with a velocity of 72 km/hr. He has to lean from he vertical approximately through an angle. A cyclist is moving on a circular track of radius 80 m with a velocity of 72 km/hr. He has to lean from he vertical approximately [...]

The position of a particle moving in the xy-plane at any time t is given by x=(3t^2 -6t) m , y=( t^2 -2t) m. Select the correct statement about the moving particle from following . a) The acceleration of the particle is zero at t=0 second b) The velocity of the particle is zero at [...]

Assertion : For a given time interval average velocity is single valued while average speed can have many values. Reason : Velocity ls a vector quantity and speed is a scalar quantity. Assertion : For a given time interval average velocity is single valued while average speed can have many values. Reason : Velocity ls [...]

Assertion : The speedometer of an automobile measure the average speed of the automobile. Reason : Average velocity is equal to total distance divided by total time taken. Assertion : The speedometer of an automobile measure the average speed of the automobile. Reason : Average velocity is equal to total distance divided by total time [...]

Statement-1 : The relative velocity between any two bodies moving in opposite direction is equal to sum of the velocities of two bodies. Statement-2 : Sometimes relative velocity between two bodies is equal to difference in velocities of the two bodies. 1. In a cricket match a batswoman hits a boundary 6 times out of [...]
