Uniform Circular Motion When an object follows a circular path at a constant speed, the motion of the object is called uniform circular motion. The word uniform refers to the speed which is uniform (constant) throughout the motion. Although the speed does not vary, the particle is accelerating because the velocity changes its direction at every point on the circular track.The figure shows a particle P which moves along a circular track of radius `r` with a uniform speed `u`.Two cars `A and B` move along a concentric circular path of radius `r_A and r_B` with velocities `v_A and v_B`
A rigid body is rolling without slipping on the horizontal surface, then match the Column I with Column II and choose the correct option from the codes given below. Column I Column II A. Velocity at point `A, i.e. v_A` p.`vsqrt2` B. Velocity at point `B, i.e. v_B` q- zero C. Velocity at point `C, i.e. v_C` r. `v` D. Velocity at point `D, i.e. v_D` s. `2v`
Three concentric spherical shells have radii a, b and c (a < b < c) and have surface charge densities σ, – σ and σ respectively. If `V_A , V_B` and `V_C` denote the Potentials of the three shells, then for c = a + b, we
