Question

Directions: Some questions (Assertion – reason type) are given below. Each question contains Statement I (Assertion) and statement II (Reason). Each question has 4 choices (a), (b), (c) and (d) out of which only one is correct. So, select the correct choice.

Statement I In a collision the momentum transfer takes place along the line of impact.

Statement II The large interaction force in collision acts along the line of impact.

• A. Statement I is true, statement II is true, statement II is a correct explanation for statement I
• B. Statement I is true, statement II is true, statement II is not a correct explanation for statement I
• C. Statement I is true, statement II is false
• D. Statement I is false, statement II is true

Answer 1

The correct option is A

Statement I is true, statement II is true, statement II is a correct explanation for statement I

Assertion:

1. The collision line is a line that runs through the mass centers of the colliding particles and lines of impact is normal to the point of contact of the masses.
2. Momentum is transferred along the line of impact in a collision.

Reason:

1. The line of impact is the direction of the interactive force during the collision between two objects.
2. So statement II is the correct explanation to statement I.

Therefore, Statement I is true, statement II is true, and statement II is a correct explanation for the statement I.

Hence option (a) is the correct answer
