Chapter 26, Problem 1PLA
Electric field lines are drawn (a) from positive charges to negative charges; (b) from negative charges to positive charges; (c) from the largest charge to the smallest charge; (d) from the smallest charge to the largest charge.
Expert Solution & Answer
To determine
The direction of electric field lines.
Answer to Problem 1PLA
Option (a) from positive charges to negative charges.
Explanation of Solution
Electric field lines are an imaginary lines that always starts from the positive charge and end at the negative charge. And the number of electric field lines is directly proportional to the total number of charge.
Conclusion:
- (a) The electric field lines always starts from positive charges and end at negative charges. Thus, option (a) is correct.
- (b) The electric field lines always starts from positive charges and end at negative charges. Thus, option (b) is incorrect.
- (c) The direction of electric field lines does not depend on the size of the charge. Thus, option (c) is incorrect.
- (d) The direction of electric field lines does not depend on the size of the charge. Thus, option (d) is incorrect.
