Two blocks connected by a spring rest on a smooth horizontal plane as shown in Fig. A constant force `F` start acting on block `m_2` as shown in the figure. Which of the following statements are not correct?

A block of mass m is at rest under the action of force F against a wall as shown in figure. Which of the following statement is incorrect?

A block is resting over a smooth horizontal plane. A constant horizontal force starts acting on it at t = 0 . Which of the following graph is correct:

A block of mass m is connected to another block of mass M by a massless spring of spring constant K . Blocks are kept on a smooth horizontal plane. Initally both the blocks the at rest and spring is unstressed. Force F is applied on M to right as shownin the figure then which of the following is correct ?

Two blocks of masses m_(1) and m_(2) are connected by an ideal sprit, of force constant k . The blocks are placed on smooth horizontal surface. A horizontal force F acts on the block m_(1) . Initially spring is relaxed, both the blocks are at rest. Which of the following statement is not true tn the watt of above system.

Three large sides blocks are kept stationary over one another as shown in the figure. A horizontal force of 20N is acting on the middle block as shown in the figure. Choose the correct statement.

Two blocks are connected by a cord passing over a small frictionless pulley and resting on frictionless planes as shown in the figure. The acceleration of the blocks is :

A block of mass m is connected to another .block of mass M by a massless spring of spring constant k. A constant force f starts action as shown in figure, then:

Two blocks are connected by a cord passing over a small frictionless pulley and resting on frictionless planes as shown in the figure The accleration of the blocks is-
