Question

if two forces of magnitude 10N and 20 N acts on a body , then their minimum resultant is

​

Answer 1

Answer:

10 N

Explanation:

resultant force = 20 - 10 = 10 N

Answer 2

Given,

The magnitudes of two forces are 10 N, and 20 N.

To find,

Minimum resultant of the two.

Solution,

When the two forces act on a specific point or a body, their maximum and minimum resultant will be given as follows.

1. The resultant of two forces will be maximum when the two forces act in the same direction, or the angle between their direction of application is 0°.
2. The resultant of two forces will be minimum when the two forces act in the opposite direction, or the angle between their direction of application is 180°.

Here, the given forces are,

$F_1=10N$, and,

$F_2=20N$

For minimum resultant, both will act in opposite directions, and due to this, the resultant of these forces can be calculated by simply subtracting the two.

That is, the resultant force F will be,

$F=F_2-F_1$

⇒ F = 20 - 10

⇒ F = 10 N.

Therefore, the minimum resultant for the given forces will be 10 N.
