In the following diagrams, all the charges have equal magnitude
Options
- AA ( ) Q; B ( ) P; C ( ) P, Q; D ( ) P
- B( A P , Q ; B P ; C P , Q ; D Q )
- C( A Q ; B P , Q ; C P ; D P , Q )
- D( A P , Q ; B P ; C Q ; D P )
Correct answer
A. A ( ) Q; B ( ) P; C ( ) P, Q; D ( ) P
Step-by-step solution
1. (A) Equilateral Triangle (+ + +) - Electric Field (E): The electric field will point outward from each charge, and at the center, the contributions from the three charges will cancel out, making the electric field zero at the center. - Potential (V): The potential due to each positive charge adds up, resulting in a positive potential. Thus, the potential at the center is not zero. - Conclusion: Potential is not zero; Electric field is zero. 2. (B) Square (- - + +) - Electric Field (E): The electric field contrib
