Question 1 :
A body has a positive charge of {tex} 8 \times 10 ^ { - 19 } \mathrm { C } {/tex}. It has:

Question 2 :
Two identical metallic spheres A and B, each carrying a charge {tex} q {/tex} repel each other with a force {tex} F {/tex}. A third metallic sphere {tex} C {/tex} of the same size but uncharged, is successively made to touch the spheres {tex} A {/tex} and {tex} B {/tex} respectively one at a time and then removed away. The new force of repulsion between {tex} A {/tex} and {tex}B{/tex} is ...... of the earlier force

Question 4 :
What is the locus of an electron projected perpendicular to a uniform electric field?

Question 5 :
A short electric dipole (which consists of two point charges, {tex} + q {/tex} and {tex} - q {/tex} ) is placed at the centre {tex} \mathrm { O } {/tex} and inside a large cube (ABCDEFGH) of length {tex} \mathrm { L } , {/tex} as shown in the figure. The electric flux emanating through the cube is :<br><img style='object-fit:contain' src="https://storage.googleapis.com/teachmint/question_assets/ISC%20-%20Class%2012/5f7c7dbd8073fe2c5706c724"><br>
