Subhasini ;

Everyone stumbles a bit while solving the physics paper, but don't ever leave a chapter for JEE main. The easiest of questions may come from the Chapter you've left. So, be prepared for all chapters.

But, specifically speaking ROTATION, ELECTROSTATICS and KINEMATICS could be considered as the chapters from where most question are asked in JEE mains physics part. These three chapters always covered almost around 40-50 % of the whole paper. So, give extra care to these subjects.

Hope this helps.
