A vector in x - y plane makes an angle of 30° with y-axis. The magnitude of y-component of vector is 2 
. The magnitude of x-component of the vector will be:
A
B
6
C
2
D
Text Solution
Verified by ExpertsThe correct answer is:
C
The angle made by the vector on x axis is
= 90° -30° =60°
Let the vector be 
.
It is given that
x component is
a x = a cos 60 °
