Question

A +11nC charge is located at the origin.

A-What is the electric field at the position (x1,y1)=(5.0cm,0cm)? Write electric field vector in component form.

Express your answers using two significant figures. Enter your answers numerically separated by a comma.

B-What is the electric field at the position (x2,y2)=(?5.0cm,5.0cm)? Write electric field vector in component form.

Express your answers using two significant figures. Enter your answers numerically separated by a comma.

C-What is the electric field at the position (x3,y3)=(?5.0cm,?5.0cm)? Write electric field vector in component form.

Express your answers using two significant figures. Enter your answers numerically separated by a comma.

D-Draw a field diagram showing the electric field vectors at these points.

The orientation of your vectors will be graded. The exact length of your vectors will not be graded.

please asnwer my problem not someone else problem, thank you

Explanation / Answer

since E=kq/r2

here E=9x109 x 11x10-9/r2=99/r2

(a)

(5.0,0)

E=99/0.052 =39600N/C

theta=0o

E=ECos0i+ESin0j=39600i+0j

(40000,0)N/C

(b)

for (5.0,5.0)

r=0.05xsqrt(2)

E=99/0.052 x 2=19800N/C

theta=45o

E=ECos45i+ESin45j=14000i+14000j

(14000,14000)N/C

(c)

for (-5.0,-5.0)

r=0.05xsqrt(2)

E=99/0.052 x 2=19800N/C

theta=225o

E=ECos225i+ESin225j=-14000i-14000j

(-14000,-14000)N/C

(d)
