Answers
Answer:
A particle moving with velocity v is acted by three forces. PQR is the vector triangle formed by these forces. The resultant velocity and effect of the forces on it.
Explanation:
It is expected to submit a diagram along with the question here. As there is no diagram, so let me try and answer to all three possibilities here.
Now let us assume that a body is acted upon by three distinct forces. First point to keep in mind is the direction of the forces that act on the object at any point.
Keeping in mind that the object is moving with a velocity v along the x axis in horizontal direction (as the direction of movement is not given), the weight of the body will be one of the forces that will be acting in the downwards direction under the effect of gravity.
In this case, the weight (force acting in downward direction) will be balanced by an upward force that is equal in magnitude but opposite in direction. These two forces will be balanced. The direction of motion of the object will depend on the magnitude of the forces acting on it.
If the force acting on the body is in opposite direction and of greater magnitude, then the body will move in the direction of the greater force and in the same direction as greater force.
If the force acting on the object is acting in the direction of motion of the object, then the direction of body will also be in the same direction as the force and will continue to move in the same direction.
In second case, the velocity of the body will be less than its original velocity as it will be opposed by force of some magnitude.
In third case, the velocity of the body will be added up to the magnitude of the force as it is applied in the same direction as the motion of the body.
