First slide
Inertial and uniformly accelerated frame of reference

Match the column-I to value of Tension in column-Il assuming mass of particle equal to m


Extreme position in simple pendulum


Conical pendulum


Cart is accelerated such that particle remains at rest as shown w.r.t. cart.


Cart is accelerating freely on the incline. Particle remains at rest w.r.t. cart as shown.



(a) As velocity = 0
    No radial acceleration


(b) Motion in horizontal plane

   no acceleration in vertical direction

  Tcos37=mg T=mg×54

(c) Acceleration of particle w.r.t. cart is zero

  Tcos53=mg T=5mg3

(d)  T=mgcos37
