Question

If a 5 N force East and a 5 N force North act on an object, what is their combined effect?

Options

• 10 N

• 0 N

• 5√2 N (approximately 7.07 N) in the northeast direction

• Cannot be added

Answer 1

5√2 N (approximately 7.07 N) in the northeast direction

Explanation:

Vectors cannot be added like simple numbers. Two perpendicular forces are added using the triangle or parallelogram law, resulting in a resultant of 5√2 N at 45° angle (northeast).
