| 1-Dont try to cram or spend more time here just read it fast and cover syllabus then practice MCQ's cheptor of same topic to check your progress. . |
| 2-Wrong options are also given but dont concentrate there, Right answer is in bold format. |
| Q1 ⇒ The electric potential due to an electric
dipole at an axial point distant r from the
dipole is related to r as r-2 [other wrong options] [Discuss in forum] |
| Q2 ⇒ charge q is divided into two parts q1, and (q - q1) what is the ratio q/q1 so that the force
between the two parts placed a given distance apart is maximum 2 : 1 [other wrong options] [Discuss in forum] |
| Q3 ⇒ The electric potential at the surface of an
atomic nucleus (z = 50) of radius 9 x 10-15 m is 8 x 106 volt [other wrong options] [Discuss in forum] |
| Q4 ⇒ A soap bubble is given a negative charge
then its radius Increases [other wrong options] [Discuss in forum] |
