When two forces are equal in magnitude & θ is the angle between them resultant force will be *?

If the angle between them is θ, then the magnitude of the resultant force is. R=2Fcosθ2.

Is it possible that the magnitude of the resultant of two forces of equal magnitude is equal to the magnitude of one of the forces?

The resultant vector from adding two equal forces cannot be the same as one of the forces. The reason is because force is a vector … two equal vectors have to point in the same direction. Thus two equal forces will always end up as a double-magnitude force in the same direction as both.

What is the angle between two equal forces when their resultant also has the same magnitude as that of the forces?

Which means that if both the forces have same magnitude and same resultant then angle between them will be 120°. I hope this information helps you.

Can the resultant of two equal forces be equal to zero?

When two forces acting on a body are in opposite directions, resultant force is equal to the difference between the two forces and acts in the direction of the larger force. Thus, resultant will be zero if the two forces are equal in magnitude and opposite in direction.

At what angle three forces of equal magnitude may act so that the resultant is equal to zero?

If the resultant of three forces is zero, each three force is the equilibrant of the other two forces. In otherwords the resultant of any two forces is equal but opposite to the third force. Angle between any two forces is 120°.

At what angle should two equal force act so that the resultant is equal to either of the force?

0o
⇒θ=0o.

Are the two forces equal in magnitude?

According to Newton’s third law, the forces on the two objects are equal in magnitude. While the forces are equal in magnitude and opposite in direction, the accelerations of the objects are not necessarily equal in magnitude.

Is it possible that the magnitude of resultant of two forces of equal?

The resultant of two forces which are equal in magnitude is equal to either of two vectors in magnitude.

How do you find the angle between two resultant forces?

  1. Square of Resultant R is R^2 = P^2 + Q^2 + 2PQ cos α,
  2. α is the angle between P and Q.
  3. tan θ = Q sin α / ( P + Q cosα), θ is the angle between R and P.
  4. If Q is doubled , and if the angle between P and the new resultant S is 90 °,
  5. tan 90 = 2Q sin α / ( P + 2Q cosα),=infinity.
  6. Therefore, P = – 2Q cosα.

What is the angle between two equal forces so that their resultant is one third of one of the forces?

The answer is theta=cos inverse -17/18.

What is the resultant force of 2 equal forces?

The resultant of two equal forces is equal to either of these forces. The angle between them is. Let each of 2 equal forces be of magnitude P and let them be inclined at angle ɑ. Then their resultant R is given by R = 2P cos (ɑ / 2), but R = P.
