If angle between two non-null vectors A""⃗ and B""⃗ is 130o and its resultant is C"⃗ then
Question
If the angle between two non-null vectors and is and its resultant is , then
Solution
It seems like you're asking for the resultant of two vectors A and B given the angle between them. Here's how you can calculate it:
The magnitude of the resultant vector C can be found using the formula:
|C| = sqrt(|A|^2 + |B|^2 + 2|A||B|cosθ)
where:
- |A| and |B| are the magnitudes of vectors A and B respectively,
- θ is the angle between vectors A and B.
Given that the angle θ is 130 degrees, you can substitute this into the formula:
|C| = sqrt(|A|^2 + |B|^2 + 2|A||B|cos130)
To find the exact value of |C|, you would need the magnitudes of vectors A and B. Once you have these, you can substitute them into the formula to find the magnitude of the resultant vector C.
