What is the magnitude of the electric field produced by a charge of magnitude 7.50 μCat a distance of (a) 1.00 m and (b) 2.00 m?
Step 1 of 5</p>
Here we need to calculate the magnitude of the electric field produced by a charge at a distance .
Step 2 of 5</p>
Electric field strength is the force exerted by the charge at point per unit charge. That is force per unit charge.
Where E is the electric field strength, F is the force and q is the charge.
The electric field strength at point A due to the test charge q, which is at a distance of r from the point A is given by,
Therefore, the electric force if there is a test charge q at point A,Force is directly proportional to the product of charges and inversely proportional to the square of distance between them,
Using above equation, the electric field strength becomes,
Step 3 of 5</p>
Substituting , and in equation 1,
Therefore, the magnitude of the electric field produced by a charge at a distance is .
