Electric field at point 3 is

See the step by step solution

Step by Step Solution

Step 1: Given Information

Given charge

Distance of point 1 from the given charge

Distance of point 3 from the given charge

Distance of point 1 from the given charge

Angle of point 2 from the given charge

Step 2: Calculation

Electric field at a point is given by the equation:

Hence,

for point 1, the magnitude of the electric field will be:

for point 2, the magnitude of the electric field will be:

for point 3, the magnitude of the electric field will be:

Since the given electric field is negative in nature, hence the points under the influence of this field will also be negative.

Hence, the component form of these electric fields can be written as:

Component form of electric field at point 1:

Component form of electric field at point 2:

Component form of electric field at point 3:

Step 3: Final answer

Hence, the electric fields in their component form for the given problem can be calculated as follows:
