Thanks sir but on questions two why Don't we use work done by gravity w=mgh since the question specified that calculate work done by gravity but we use work done by friction
On question A14: the answer is C This is because when a negatively charged rod is brought near the two spheres the R will develop positive charges while repelling all the negative charges towards S
Q14.c
Why I said c,is because the polythene rod was negatively charged and for separation to occur R needs to be attracted to the negatively charged rod 😊
Please continue with your good teaching, you are really helping
Q11, the answer is C because 2+2=4
