Question

Consider the statements for an oblique collision of two sphere having different masses and initial velocities;

Statement 1: Initial and final velocity of both the spheres perpendicular to line of impact will remain same.
Statement 2: Impulse due to collision of the spheres will not affect initial velocity of sphere along the line of impact.

• A. Statement 1 is true but statement 2 is false.
• B. Statement 2 is true but statement 1 is false.
• C. Both statements are true.
• D. Both statements are false.

Answer 1

The correct option is A Statement 1 is true but statement 2 is false.

As we know,
No component of impulse due to collision of sphere acts along common tangent (perpendicular to L.O.I). Therefore, initial and final velocity of both sphere perpendicular to line of impact will remain same.

Impulse due to collision of sphere may affect initial velocity of sphere along the line of impact.

$\therefore$Statement 1 is true but statement 2 is false.
