Question

In the case of a oscillating simple pendulum, if the air resistance is taken into consideration, then ____.

• A. amplitude of an oscillation remains the same.
• B. frequency remains the same.
• C. the resultant acceleration remains the same
• D. All the above

Answer 1

The correct option is B frequency remains the same.

Frequency of oscillation of simple pendulum remains the same but amplitude of oscillation decreases due to air resistance (damped oscillation).
