Question

There are 3 point charges at the given locations. Charge 1 is 5.19 nC at x=0.89 m, charge 2 is 5.6 nC at y=0.7m, and charge 3 is -1.98 nC at x=-0.68 m and y=0.3 m

Part A: Calculate the magnitude of the electric field produced by charge 1 at the origin?

Answer: E1= 58.9 N/C

Part B: What is the direction of the electric field produced by charge 1 at the origin?

Answer: In the -x direction

Part C: Calculate the electric field produced by charge 2 at the origin?

Answer: E2= 103 N/C

Part D: What is the direction of the electric field produced by charge 2 at the origin?

Answer: In the -y direction

Part E: Calculate the magnitude of the electric field produced by charge 3 at the origin?

Answer: E3= 32.2 N/C

Part F: Calculate the x component of the net electric field at the origin?

Ex=______N/C

Part G: Calculate the y component of the net electric field produced at the origin?

Ey=_____N/C

Part H: Calculate the net electric field at the origin?

E=_____N/C

Part I: What is the direction of the net electric field at the origin? Give an acute ( < 90 degrees) angle with respect to the -x axis. (How many degrees above or below the -x axis)

Explanation / Answer

part A,................................................................................................................................................

E1 = KQ1 / (r1)^2 = 9*10^9*5.19*(10^-9) / 0.89 = 58.9 N/C...............................................................

part B : now imagine the charge on a coordinate plane. it is on x = 0.89 m and it is positively charged. field direction is away from the charge, hence at origin, it is towards negative x direction...................

part C :u can do this the same way i did part 1. just substitute the appropriate values in the formula......

part D : explanation similar to that of part B...........................................................................

part E - explanation similar to that of part A...........................................................................

so, now u can solve the rest as u have all the values
