# Physics Quiz on Equilibrium of Forces for IIT JEE, NEET, Medical & Engineering Exam

0 ## Physics Quiz on Equilibrium of Forces

Physics Quiz on Equilibrium of Forces: Previous trends reveal that NEET aspirants find Physics as the most challenging section amongst the other sections. But most of them fail to decipher the reason behind this. This particularly can be as the candidates taking up this examination are predominantly medical aspirants with their subject of interest being Biology. Also, sections like Physics are more on theories, laws, numerical as opposed to Biology which is more of fact-based, life sciences and comprising of substantial explanations. In this post we are providing you Physics quiz on Equilibrium of Forces.

## Physics Quiz on Equilibrium of Forces

1. Consider the blocks shown in the diagram to be pushed against a frictionless table by a constant force. Following statements are said about the blocks:

• All blocks move with the same acceleration
• The net force on all the blocks is the same

Which of these statements is true?

1. Both A and B
2. Neither A and B
3. Only A
4. Only B

(c) Only A

2. The resultant of the two forces are perpendicular to the smaller of the two forces. The magnitude of one of the forces is double the magnitude of the other force. What is the angle between the forces?

1. 600
2. 900
3. 1200
4. 1500

(c) 1200

3. Which of the following is true when a body is stationary?

1. The force acting on it is not in contact with it
2. The body is in vacuum
3. There is no force acting on it
4. The combination of forces acting on it balance each other

(d) The combination of forces acting on it balance each other

4. Two forces with magnitude F have the resultant of same magnitude F. What is the angle between the forces?

1. 450
2. 600
3. 1200
4. 1500

(c) 1200

5. How is the weight of the aeroplane flying in the air balanced?

1. The weight is balanced because of the force due to the pressure difference between the upper and lower surfaces of the wings created by different airspeeds on the surfaces.
2. The weight is balanced due to the vertical component of the thrust created by air currents striking the lower surface of the wings
3. The weight is balanced due to the force produced when the reactions of gases are ejected by the revolving propellor.
4. Upthrust of the air which will be equal to the weight of the air having the same volume as the plane

(a) The weight is balanced because of the force due to the pressure difference between the upper and lower surfaces of the wings created by different airspeeds on the surfaces.

6. In which direction should the force be applied to balance a force in the direction of North-East direction?

1. South
2. West
3. South-West
4. North-East

(c) South-West

7. Among the following which cannot be a resultant force of 5 N and 10 N?

1. 4 N
2. 5 N
3. 8 N
4. 12 N

(a) 4 N
