Identify the correct statements : A. Electrostatic field lines form closed loops. B. The electric field lines point radially outward when charge is greater than zero. C. The Gauss-Law is valid only for inverse-square force. D. The workdone in moving a charged particle in a static electric field around a closed path is zero. E. The motion of a particle under Coulomb's force must take place in a plane. Choose the correct answer from the options given below:

1. (1) A, B, D, E Only
2. (2) A, B, C, D Only
3. (3) B, C, D, E Only
4. (4) A, C, E Only

Correct answer: (3) B, C, D, E Only

Solution

Option B is correct because electric field lines do point outward from positive charges, the work done in a static electric field around a closed path is indeed zero, and while Gauss's Law is commonly associated with inverse-square forces like gravity and electrostatics, it can be applied to other fields as well. However, the motion of a charged particle under Coulomb's force is constrained to a plane due to the nature of the force being central.
