The electric field strength at a distance r from a charge q is E.what ...
Understanding Electric Field Strength
The electric field strength (E) created by a point charge (q) at a distance (r) is determined by Coulomb's law. The relationship can be expressed as:
E = k * |q| / r²
where k is Coulomb's constant.
Effect of Increasing Distance on Electric Field Strength
When the distance from the charge is doubled (increased to 2r), we can analyze the new electric field strength (E'):
- Original Distance: E = k * |q| / r²
- New Distance: E' = k * |q| / (2r)²
Now, substituting the new distance into the equation:
- E' = k * |q| / (4r²)
- E' = (1/4) * (k * |q| / r²)
- E' = E / 4
Conclusion
Thus, when the distance is increased to 2r, the electric field strength is reduced to a quarter of its original value.
Final Answer
- The correct answer is 2. E/4.
This demonstrates the inverse square nature of the electric field with respect to distance, emphasizing that as you move away from a charge, the electric field strength decreases significantly.
