Question

" the angle between two forces increases, the magnitude of their resultant
(1) decreases
(2) increases
(3) remains unchanged
(4) first decreases and then increase
​

Answer 1

Answer:

Option 4

Explanation:

The magnitude of the resultant vector depends on the value of cosine of the angle between the vectors.

As angle's measure approaches from 0 to 90 degrees, cosine of an angle decreases and then from 90 to 180 degrees it increases once again. Therefore, cosine has a range of [ -1 , 1 ]

Answer 2

Answer:

the answer is 1

Explanation:

when angle is 60 bw resultant then magnitude of their resultant is √3F

if angle 90....magnitude is √2F

if angle 120.....magnitide is F

so from this.....the answer seems 1
