Question

4. Explain Resolution of forces using an example.

5. The resultant of all forces acting on a body in equilibrium is __________

a) Zero

b) Maximum c) Positive

d) Negative

6. If two forces are acting on a body, explain how the resultant force can be calculated using:

a. Parallelogram law of forces b. Triangular law of forces

7. Using the Parallelogram law of forces, find the resultant of the vector represented by 9N and 10N

acting in the direction and making an angle of 600.

8. Law of polygon of forces is similar to triangular law of forces. Explain how we can use the Law of

polygon of forces to find the resultant of more than 2 forces acting on a body.​
