THE RESULTANT OF TWO FORCES ACTING ON AN OBJECT IS MAXIMUM IF THE ANGLE BETWEEN THEM IS

• A. 45°
• B. 0° ✓
• C. 90°
• D. 180°

The answer to the question is: B. 0°

The resultant of two forces acting on an object is maximum when the angle between them is 0°. This can be explained using the concept of vector addition. When two forces act on an object, their combined effect can be determined by adding them as vectors. The magnitude and direction of the resultant force depend on the magnitudes and directions of the individual forces as well as the angle between them.

When the two forces are acting in the same direction (angle = 0°), their combined effect is maximized because they are reinforcing each other. In this case, the magnitude of the resultant force is equal to the sum of the magnitudes of the individual forces. As the angle between the forces increases from 0° to 90°, the magnitude of the resultant force decreases. At an angle of 90°, the forces are acting perpendicular to each other, resulting in a smaller magnitude for the resultant force. When the angle reaches 180°, the forces are acting in opposite directions, leading to cancellation and a minimum resultant force.

Therefore, based on vector addition principles, it can be concluded that the maximum resultant force occurs when the angle between two forces is 0°.
