Which of the following is the correct order of forces?

Three forces starts acting simultaneously on a particle moving with velocity u. These forces are represented in magnitude and direction by the three sides of a triangle ABC (as shown). The particle will now move with velocity C

Two forces are such that the sum of their magnitudes is 18 N and their resultant is perpendicular to the smaller force and magnitude of resultant is 12 N. Then the magnitudes of the forces are

When forces F1, F2, F3 are acting on a particle of mass m such that F2 and F3 are mutually perpendicular, then the particle remains stationary. If the force F1 is now removed, then the acceleration of the particle i e is

A block of mass M is pulled along a horizontal frictionless surface by a rope of mass m. If a force P is applied at the free end of the rope, the force exerted by the rope on the block will be

One end of a massless rope, which passes over a massless and frictionless pulley P is tied to a hook C while the other end is free. Maximum tension that the rope can bear is 360 N. with what value of minimum safe acceleration (in ms 2) can a monkey of 60 kg move down on the rope

A light string passing over a smooth light pulley connects two blocks of masses m, and m2 (vertically). If the acceleration of the system is g/8 then the ratio of the masses is

An air column, closed at one end and open at the other. resonates with a tuning fork when the smallest length of the column is 50 cm. The next larger length of the column resonating with the same tuning fork is

A light string passing over a smooth light pulley connects two blocks of masses m, and m2 (vertically). If the acceleration of the system is g/4 then the ratio of the masses is

Two masses m1 =5kg and m2 = 4.8 kg tied to a string are hanging over a light frictionless pulley. What is the acceleration of the masses when they are free to move
