AIPMT PRELIMS 2003 Physics Tangential Acceleration MCQ Question
Type: MCQ-numerical-Hard-Class 11
A particle moves along a circle of radius (20/π) m with constant tangential acceleration. If the velocity of the particle is 80 m/s at the end of the second revolution after motion has begun, the tangential acceleration is :
A
40 m/s²
B
640 π m/s²
C
160 π m/s²
D
40 π m/s²
Correct Answer
Option A
Detailed Explanation
Using the formula v² = u² + 2as, where s is the distance covered in two revolutions (2 × 2πr), we can solve for the tangential acceleration.
