Three point particles  A,B and C, of masses m,ηm and 2m respectively, are in equilibrium, with the help of strings, as shown:The horizontal level of  A and C is same and the two inclined strings are equal in length. If the ratio of tensions in the two vertical strings is 1.5, findη.

Two masses m1 and m2 placed on a smooth horizontal surface are connected by a mass less, inextensible string. A horizontal force F is applied on m2 as shown in the figure, the tension in the string is 1 point

Determine the tension in the string connecting the 2.00 kg and 1.00 kg masses.

Two stones of masses m and 2m are whirled in horizontal circle as shown in figure. Then T1T2 is(T1 & T2 are tensions in the string as indicated in figure)

A particle is suspended from a string of length R. It is given a velocity u = 3  at the lowest point.           Column I                       Column II    (A) Velocity at B                   (P) 7 mg        (B) Velocity at C                   (Q)         (C) Tension in string at B     (R)        (D) Tension in string at C     (S)    4 mgA-R; B-Q; C-P; D-S    A-Q; B-R; C-S; D-PA-R; B-P; C-Q; D-SA-P; B-S; C-R; D-Q

Two blocks A and B of masses 3 m and m respectively are connected by a massless and inextensible string. The whole system is suspended by a massless spring as shown in figure. The magnitudes of acceleration of A and B immediately after the string is cut, are respectively :-    [2017]A: B: g, gC: D:
