A train is moving along a horizontal track. A pendulum suspended from the roof of the train makes an angle of 5° with the vertical. The acceleration of the train is

A body of weight 100 N is suspended with the help of strings as shown in figure. 

 For a body along the inclined plane, the normal reaction acts

Two forces F₁ and F₂ are acting on a particle. The particle will remain at rest if two forces are

 If no resultant force acts on a body then the body will be in

A body is at rest though forces act on it. Then

In mechanics, if the net external force on the particle is zero, then the particle is said to be in state of

A book is lying on the table. What is the angle between the action of the book on the table and reaction of table on the book?

A mass of 6 kg is suspended by a rope of length 2 m from a ceiling. A force of 50 N in the horizontal direction is applied at the mid-point of the rope, as shown. What is the angle the rope makes with the vertical in equilibrium?

Which of the conditions shows that the particles are in equilibrium state for two forces F₁ and F₂ acting on the body?

Which of the following forces is not considered as a contact force in Mechanics?

Weight and normal reaction forces

The contact forces of mechanics are fundamentally derived from

The minimum angle that an inclined plane makes with the horizontal when a body placed on it just begins to slide down is called

A body in equilibrium

Spring force is a restoring force.

The forces F₁, F₂, and F₃ are acting on a particle of mass m, such that F₂ and F₃are mutually perpendicular and under the effect of F₁, F₂, and F₃ , the particle remains stationary. What will be the acceleration of the particle, if the force F₁ is removed?

Tension on an almost massless rope being pulled by two boys, one small and one big, will be

Which of the following cannot be regarded as yet another kind of force?

The component of contact force normal to the surfaces in contact is called
