RESOLUTION OF FORCES

Forces of magnitude 8 N and 5 N act on a body as shown in the diagram alongside. Ava and Scarlett are trying to calculate the resultant force acting at O. Can you help them find the answer, correct to 2 decimal places?

• 8.26N

• 9.83N

• 13.00N

• 14.06N

• 9.2N

• 84.0N

• 13.0N

• 9.0N

Find the magnitude and direction of the resultant of two forces 5N and 12N acting at right angles to each other.

• 13N, 22.6°

• 5N, 15.5°

• 10N, 18.1°

• 15N, 22.8°

Forces 90N and 120N act in the directions 120° and 240° respectively. Find the resultant of these forces.

Can you help Michael, Luna, and William solve this interesting problem?

• 14.11N

• 13.81N

• 12.06N

• 11.05N

Forces A and B act at a point O. The magnitude of A is 9N and that of B is 13N. If the angle between them is 50°, find the resultant force to the nearest whole number.

• 400N

• 99N

• 45N

• 20N

• 135°

• 045°

• 225°

• 315°
