Two force each of 10N acts on a body, one towards the north and the other towards the east.
The magnitude and the direction of the resultant force are
- 20N, 45°E
- 20N, 45°W
- 10√2N, 45°W
-
10√2N, 45°E
The correct answer is: D
Explanation
From Pythagoras,R2 = 102 + 102
= 100 + 100
= 200
therefore R2 = √200 = √2 x 100
= 10√2, in the direction 45°E
