NEET 2016 Physics Tangential Acceleration MCQ Question
Type: MCQ-numerical-Hard-Class 11
A particle of mass 10 g moves along a circle of radius 6.4 cm with a constant tangential acceleration. What is the magnitude of this acceleration, if the kinetic energy of the particle becomes equal to 8 × 10⁻⁴ J by the end of the second revolution after the beginning of the motion?
A
0.18 m/s²
B
0.2 m/s²
C
0.1 m/s²
D
0.15 m/s²
Correct Answer
Option C
Detailed Explanation
Using the work-energy principle, the work done by the tangential force equals the change in kinetic energy. Solving for acceleration gives the correct value.
