Hello Sir,

He is just at the age of 5 or 6; let him play around. After his play, you ask him to explain the things he has done the whole day, you listen to him and make a good conversation, and then you make him sit for studies, he'll do your words. Simple logic in parenting, if you want to make him sit, you should sit with him patiently.

Hi,

For the primary classes, it is better to have whiteboard classes to make them active in an online session. If we do another screen share like a session, the student won't listen, and they might get distracted. You can also add some pics, vids to your whiteboard for clear a concept or topic.

Thanks!

Capacitance of the capacitor, C = 600 pF

Potential difference, V = 200 V

Electrostatic energy stored in the capacitor is given by,

If supply is disconnected from the capacitor and another capacitor of capacitance C = 600 pF is connected to it, then equivalent capacitance (C^') of the combination is given by,

New electrostatic energy can be calculated as

Loss in electrostatic enegy = E - E'

                                        = 1.2 x 10^-5  -  0.6 x 10^-5

                                        = 0.6 x 10^-5

                                        = 6 x 10^-6 J 

Therefore, the electrostatic energy lost in the process is 6 x 10^-6 J.
