A force of 20 N acts toward the west. Another force acts at the same point so that the resultant of the two forces is zero. What is the magnitude and direction of the second force?
To find the magnitude and direction of the second force, we need to use the concept of vector addition.
Given:
- Force 1: 20 N towards the west
If the resultant of the two forces is zero, it means the second force must have the same magnitude but act in the opposite direction to cancel out the first force.
Since Force 1 acts towards the west, the second force must act towards the east.
Magnitude of Force 2 = Magnitude of Force 1 = 20 N
Direction of Force 2 = Opposite direction to Force 1 = East
So, the magnitude of the second force is 20 N, and its direction is towards the east.
To find the magnitude and direction of the second force, we need to analyze the given information.
Given:
- The force of 20 N acts toward the west.
- The resultant of the two forces is zero.
Since the resultant is zero, it means that the two forces are equal in magnitude but opposite in direction. This implies that the second force must have the same magnitude (20 N) as the first force, but act in the opposite direction.
Therefore, the magnitude of the second force is 20 N, and the direction is toward the east (opposite to the first force, which is toward the west).
