C) Y is the strongest point in the electric field.
Answer:
a) 38.27 b) 322.5°
c) 126.99 d) 1.17°
e) 62.27 e) 139.6°
Explanation:
First of all we have to convert the coordinates into rectangular coordinates, so:
a=( 43.3 , 25)
b=( -48.3 , -12.94)
c=( 35.36 , -35.36)
Now we can do the math easier (x coordinate with x coordinate, and y coordinate with y coordinate):
1.) a+b+c=( 30.36 , -23.3) = 38.27 < 322.5°
2.) a-b+c=( 126.96 , 2.6) = 126.99 < 1.17°
3.) (a+b) - (c+d)=0 Solving for d:
d=(a+b) - c = ( -40.36 , 47.42) = 62.27 < 139.6°
Any vector which is made in x-y plane will have some angle with the x axis
in that case we can say that
also for Y direction we can say
so here the two components of vector is given by Px and Py
so we can say that
so correct answer would be
<em>Vectors Px and Py are components of vector P.</em>
d because the pressure particals won't have a small space to bump to
