Sir agr question reverse ho jaye tb kya krna hoga? I mean, agr question me pehle hi bta de ki net force 0 hoga aur hme Unknown charge Q ka value nikalna hai in terms of q. to use kaise solve krenge??

[@sanjamsingh7821]

Sir jab apne side ke value nikali tab ham pathagorus theorem se bhi to nikal sakte hai? Hame pata hai cd=l/2 Ac= l hai to use ad nikal jiaga or use hum centroid ke fotmula se nikal lenge

[@sameenaanjum6596]

Thank you. You explained in a very good way. In text they took many short cuts.

[@PenPineapple123]

Thank you so much sir!!! This was very helpful. But sir to find length of AD median why can't we use Pythagoras theorem by taking AC as L and DC as L/2?

[@vedanshchoutala2920]

It will take much time and the values will come in root which will be very complicated to solve Just for 3 marks .......

Two equal positive charges Q are fixed at points (a, 0) and (-a, 0) on the x - axis. An opposite charge -q at rest is released from point (0, a) on the y-axis. The charge -q will 1)move to infinity 2)move to origin and rest there 3)Undergo SHM about the origin 4)execute oscillatory periodic motion but not SHM Sir please ye question ka video solution upload kijiye
