Question

Assertion : A spring block system is kept over smooth surface as shown in figure. If a constant horizontal force F is applied on the block it will start oscillating simple harmonically.

Reason : Time period of oscillation is less than 2pi√(m/k)

(a) If both Assertion and Reason are true and the Reason is correct explanation of the Assertion 

(b) If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

(c) If Assertion is true, but the Reason is false.

(d) If Assertion is false but the Reason is true.

Answer 1

Correct option (c) If Assertion is true, but the Reason is false.

Explanation :

Asserion is true while time period of oscillation is 2pi√(m/k), so, the reason is false.
