The electric field in an xy plane produced by a positively charged particle is 8.55(4.5 3.0 ) N/C at the point (4.2, 4.9) cm and
126 N/C at the point (2.2, 0) cm. What are the (a) x and (b) y coordinates of the particle
1 answer:
Answer:
(a) x=-3.15cm
(b)y=0cm
Step-by-step explanation:
Locate the point (4.2,4.9) cm and draw the vector 4.5i+3.j with the origin at this point, the end of the vector is going to be in the point (8.7,7.9). With point (2.2,0), after searching, draw a line to the right to represent that the direction of the field is toward the positive x-axis.
Draw a line in each point in the opposite direction of the field in that point, the point where these lines intersect each other is the position of the particle.
Is the point (-3.15,0)cm
(a) x=-3.15cm
(b)y=0cm

Answer:
a)g: 3x + 4y = 10 b) a:x+y = 5 c) c: 3x + 4y = 10
h: 6x + 8y = 5 b:2x + 3y = 8 d: 6x + 8y = 5
Step-by-step explanation:
a) Has no solution
g: 3x + 4y = 10
h: 6x + 8y = 5
Above Equations gives you parallel lines refer attachment
b) has exactly one solution
a:x+y = 5
b:2x + 3y = 8
Above Equations gives you intersecting lines refer attachment
c) has infinitely many solutions
c: 3x + 4y = 10
d: 6x + 8y = 5
Above Equations gives you collinear lines refer attachment
i) if we add x + 2y = 1 to equation x + y = 5 to make an inconsistent system.
ii) if we add x + 2y = 3 to equation x + y = 5 to create infinitely system.
iii) if we add x + 4y = 1 to equation x + y = 5 to create infinitely system.
iv) if we add to x + y =5 equation x + y = 5 to change the unique solution you had to a different unique solution
