A vector of magnitude 6 unit makes an angle of 60° with x-axis.
The component of vector along x-axis has magnitude
O 1 unit
O2 unit
3 unit
O 5 unit
Answers
Answer:
3 Unit
Explanation:
If the vector of 6 unit makes an angle of 60 degree with the x axis, then its projection along the x axis would be 6cos 60⁰
= 3 unit
Given : A vector of magnitude 6 unit makes an angle of 60° with x-axis.
To Find : The component of vector along x-axis has magnitude
Solution:
A vector of magnitude 6 unit makes an angle of 60° with x-axis.
The component of vector along x-axis has magnitude = 6 Cos60°
= 6 ( 1/2)
= 3
The component of vector along x-axis has magnitude = 3 units
Additional Info :
The component of vector along y-axis has magnitude = 6 Sin60°
= 6 (√3/2)
= 3√3
The component of vector along x-axis has magnitude 3 units
