ar and at represent radial and tangential accelerations respectively. The motion of the particle is uniformly circular only if (A) ar = 0 and at = 0 (B) ar = 0 and at ≠ 0 (C) ar ≠ 0 and at = 0 (D) ar ≠ 0 and at ≠ 0 |

Answer» Answer is (B) ar = 0 and at ≠ 0 If ar = 0, there is no radial acceleration and circular motion is not possible So ar ≠ 0 If at ≠ 0 the motion is not uniform as angular velocity will change So ar ≠ 0 and at = 0 for uniform circular motion |
