A force of 50N moves a body:
I. Friction force exerted on the body is less than 50N
II. Friction force exerted on the body is more than 50N
III. None of these
IV. Both of I and II

Academic Physics NCERT Class 9

Because the force of 50 N moves the body. Therefore, the friction force exerted on the body is less than 50N.

Therefore, option I is correct.

The rate of change of momentum of an object is proportional to I. Mass of the body II. Velocity of the body III. Net force applied on the body IV. None of these
A book is lying on the horizontal table top. If we tilt the table a little, then the book starts sliding down slowly. This happens because:(a) sliding friction is greater than static friction(b) sliding friction is less than force of gravity(c) static friction is greater than sliding friction(d) force of gravity is less than sliding friction
What is force of friction?
According to the third law of motion when a body exerts a force on another body then the other body also exerts force and both are equal and opposite. So when earth exerts a force on a falling apple then the force of the same magnitude should be exerted by the apple also towards earth. So why don't the earth moves towards the apple as force is equal?
Is there any force exerted on the human body by wind? If yes, which one and how?
What is the direction of force of friction acting on a moving object?
Which of the following statements is incorrect?(a) static friction is greater than rolling friction(b) sliding friction is less than rolling friction(c) rolling friction is less than static friction(d) static friction is greater than sliding friction
Which one of the following forces is a contact force?$(a)$. Force of gravity $(b)$. Force of friction$(c)$. Magnetic force $(d)$. Electrostatic force
Define force of friction.
Give one example each where:(a) a force moves a stationary body.(b) a force stops a moving body.(c) a force changes the speed of a moving body.(d) a force changes the direction of a moving body. (e) a force changes the shape (and size) of a body.
Using a horizontal force of 200 N, we intend to move a wooden cabinet across a floor at a constant velocity. What is the friction force that will be exerted on the cabinet?
A gas filled balloon moves up. Is the upward force acting on it larger or smaller than the force of gravity?
A gas-filled balloon moves up. Is the upward force acting on the balloon larger or smaller than the force of gravity?
Work done by the centripetal force is:(a) zero(b) infinity(c) more than zero(d) none of these
