[PDF ] Download 11years of AIEEE chapter wise solutions for JEE MAIN by MTG The 11th edition of JEE Main topic-wise Solved Papers (2002 - 19) Question 1. Thus, like the potential energy of a mass in a gravitational field, we can define the electrostatic potential energy of a charge in an electrostatic field. The value of e/m of these particles was found to be the same as that for cathode ray particles. How could an atom as simple as hydrogen, consisting of a single electron and a single proton, emit a complex spectrum of specific wavelengths? When an external force does work in taking a body from a point to another against a force like spring force or gravitational force, that work gets stored as the potential energy of the body. Solving the questions present in the textbooks is not an easy task. NCERT Exemplar Books will surely help students to score well in examinations. Students have to be more focussed about their studies as this is the start of their future learning and career. The interrelation between magnetism and electricity was first observed by a Danish physicist, Hans Christian Oersted. Before we discussed the Pradeep Book Solution for Class 12. The flow of charges in lightning is not steady, but in our everyday life, we see many devices where charges flow in a steady manner, like water flowing smoothly in a river.
