Chapter 1 of Class 12 Maths Relations and Functions explores fundamental concepts like types of relations and functions. It covers empty, universal, reflexive, symmetric, transitive, and equivalence relations along with one-one, onto, and bijective functions. MCQs assess understanding of relation ...
Electric field lines contract lengthwise because they represent the force experienced by a positive test charge in the field. This contraction indicates the attraction between opposite charges, as field lines always originate from positive charges and terminate at negative charges, ...
When a neutral balloon is charged, its size increases. This happens because like charges repel, causing the charged particles on the balloon’s surface to push apart. This increases the internal electrostatic pressure, slightly expanding the balloon. Thus, the correct answer ...
According to Gauss’s Law, the total electric flux (Φ) through a closed surface is given by: Φ = Qenclosed/ε0 where Qₑ is the total charge enclosed within the surface. The total charge enclosed is: Q enclosed = (+8Q) + (-3Q) ...
