চিত্রে দেখানো সিস্টেমে। m_(1) gt m_(2)। সিস্টেমটি থ্রেড বিসি দ্বারা বিশ্রামে অনুষ্ঠিত হয়। এখন থ্রেড...

Two masses m_(1) and m_(2) are attached to a spring balance S as shown in figure. m_(1) gt m_(2) then the reading of spring balance will be . .

A gas mixture consists of molecules of type 1,2 and 3, with molar masses m_(1) gt m_(2) gt m_(3).V_(rms) " and "overset(-)(K) are the r.m.s. speed and average kinetic energy of the gases. Which of the following is true-

In the system shown in fig. m_(1) gt m_(2) . The system is held at rest by thread BC. Now thread BC is burnt. Answer the following: Just after burning the thread, what is the acceleration of m_(2) ?

Two particles of mass m_(1) and m_(2)(m_(1) gt m_(2)) are attached to the ends of a light inextensible string passing over a smooth fixed pulley. When the level of m_(1) is higher than that of m_(2) by 49 cm and string is just taut m_(2) is released. 0.5 s after motion started the masses are at the same level. the ratio of m_(1) to m_(2) is (Take g=9.8ms^(-2) )

In the system shown in fig. m_(1) gt m_(2) . The system is held at rest by thread BC. Now thread BC is burnt. Answer the following: Just after burning the thread, what is the tension in the spring?

In the system shown in fig. m_(1) gt m_(2) . The system is held at rest by thread BC. Now thread BC is burnt. Answer the following: Before burnig the thread, what are the tensions in spring and thread BC, respectively?

In the system shown in figure m_(1) gt m_(2) . System is held at rest by thread BP. Just after the thread BP is burnt :

In the system shown in the figure m_(1) gt m_(2) . System is held at rest by thread BC. Just after the thread BC is burnt :

For the system shown in fog. m_(1) gt m_(2) gtm_(3) gt m_(4) . Initially, the system is at rest in equilibrium condition., if the string joining m_(4) and ground is cut, then just after the string is cut. Statement I: m_(1), m_(2), m_(3) remain stationary. Statement II: The value of acceleration of all the four blocks can be determined. Statement III: Only m_(4) remain stationary. Statement IV: Only m_(4) accelerates.
