Read the assertion and reason carefully to mark the correct option out of the options given below. (A) If both assertion and reason are true and the reason is the correct explanation of the assertion. (B) If both assertion and reason are true but reason is not the correct explanation of the assertion, (C) If assertion is true but reason is false. (D) If the assertion and reason both the false. (E) If assertion is false but reason is true. Assertion: Two short magnets are placed on a cork which floats on water. The magnets are placed such that the axis of one bisects the axis of other at right angles. Then the cork has neither translational nor rotational motion. Reason: Net force on the cork is zero.

Key Concepts

Assertion-Reason Questions

These questions involve evaluating two statements: an assertion and a reason. The task is to check whether both statements are true and whether the reason logically explains the assertion. This type of question tests both factual understanding and the ability to analyze the connection between two related concepts.

Translational Equilibrium

Translational equilibrium occurs when the net external force acting on an object is zero. In such a case, the object does not experience any acceleration, meaning there is no change in its motion along a straight line.

Rotational Equilibrium

Rotational equilibrium is achieved when the net external torque acting on an object is zero. This condition ensures that there is no angular acceleration, so the object will not start to rotate or change its rotational state.

Net Force vs. Net Torque

It is important to differentiate between net force and net torque when analyzing the motion of objects. While a net force of zero prevents translational motion, a net torque of zero is required to prevent rotational motion. Both aspects must be considered to fully explain the static behavior of a system.
