Teaching HTET PGT Level 3 - 2024 Mock Test Physics Motion in Two and Three Dimensions Circular motion
For a particle in uniform circular motion, the acceleration a at any point P(R, θ) on the circular path of radius R is (when θ is measured from the positive x-axis and v is uniform speed):
1
\(\rm -\frac{V^2}{R} \sin \theta \hat{i}+\frac{V^2}{R} \cos \theta \hat{j} \)
2
\(\rm -\frac{V^2}{R} \cos \theta \hat{i}+\frac{V^2}{R} \sin \theta \hat{j} \)
3
\(\rm -\frac{V^2}{R} \cos \theta \hat{i}-\frac{V^2}{R} \sin \theta \hat{j} \)
4
\(\rm -\frac{V^2}{R} \hat{i}+\frac{V^2}{R} \hat{j}\)
