In all the four situations depicted in Table-1, a ball of mass `m` is connected to a string. In each case, find the tension in the string and match the appropriate entries is Table-2

Answer

[A-Q,R,S],[B-P,S],[C-Q,S],[D-R]

Explanation

(A) `T cos theta = mg` and `T sin theta = (mv^(2))/(R )`
(B) In extreme position, net force along the string = 0 `:. T = mg cos theta`
(C ) `T cos theta = mg` and `T sin theta = m a`
Since, ball is accelerated, velocity of the ball with respect to ground is changing continuously
(d) Velocity = constant `:. a_("net") = 0` `:. F_("net") = 0` or T = mg
