Two forces F1=5N and f2=15N are acting on a body in opposite direction...
**Solution:**
Given:
- Force F1 = 5N
- Force F2 = 15N (opposite direction)
To find:
- Work done by force F1
**Calculating the net force:**
Since the two forces are acting in opposite directions, we can find the net force by subtracting the smaller force from the larger force.
Net force = | F2 - F1 |
= | 15N - 5N |
= | 10N |
= 10N (magnitude)
**Calculating the displacement:**
The body is placed by 5m in the direction of the net force. This means that the displacement is 5m.
Displacement = 5m
**Calculating the work done:**
The work done by a force can be calculated using the formula:
Work done = Force * Displacement * cos(theta)
Where theta is the angle between the force and displacement vectors. Since the force and displacement vectors are in the same direction, the angle theta is 0 degrees.
Therefore, the formula becomes:
Work done = Force * Displacement * cos(0)
= Force * Displacement
Substituting the values:
Work done by F1 = 5N * 5m
= 25 Nm
= 25 Joules
Therefore, the work done by the force F1 is 25 Joules.
Given:
- Force F1 = 5N
- Force F2 = 15N (opposite direction)
To find:
- Work done by force F1
**Calculating the net force:**
Since the two forces are acting in opposite directions, we can find the net force by subtracting the smaller force from the larger force.
Net force = | F2 - F1 |
= | 15N - 5N |
= | 10N |
= 10N (magnitude)
**Calculating the displacement:**
The body is placed by 5m in the direction of the net force. This means that the displacement is 5m.
Displacement = 5m
**Calculating the work done:**
The work done by a force can be calculated using the formula:
Work done = Force * Displacement * cos(theta)
Where theta is the angle between the force and displacement vectors. Since the force and displacement vectors are in the same direction, the angle theta is 0 degrees.
Therefore, the formula becomes:
Work done = Force * Displacement * cos(0)
= Force * Displacement
Substituting the values:
Work done by F1 = 5N * 5m
= 25 Nm
= 25 Joules
Therefore, the work done by the force F1 is 25 Joules.
