In case of delay in answering the questions, such questions will be posted on to the website to enable the visitors to post answer as comments.
Simple questions can be asked through the comment system too.
sir my ques. is In annihilation concept of chp. electrostatics why e- + e+ -> 2gamma ray photon,
The question is not fully clear. If your question is Why TWO gamma rays, I would recommend to go through the following link Click Here for More information
Further, I request you to post detailed questions and doubts here.
Thank you

sir when we climb up a rope with acceleration how do tension helps in that please explain
Use Newton’s laws of motion and free body diagrams. When we are at rest or moving up or down without acceleration, our weight will be equal to T.
But when moving with acceleration, it will be different. While climbing up with acceleration, ma = T-mg
or T = m(a+g)
when we climb up then rope is very tight because of our weight. then tension is greater than weight so climb. there ma=T-mg (because tension is greater)you right admin
yes; T= m(a+g) while climbing up
is electric field intensity,,,,and electric field strength is same

b) d=q/e0
c) d=e.e0
d) d=none
the point at which 2 parallel lines meet is called
INFINITY …… a basic concept forgotten by most of the people
specific resistance of copper wire is 1.6 into 10 rest to the power -8 ohm.m. What happens to its specific resistance and resistance if one meter long wire is cut in to two pieces??
plz answer it.
a charge q is placed at the center of the line joining two equal charges Q.Show that the system of three charge will be of equilibrium,if q=-Q/4?
two electrons and a positive charge q are held along at straight line.At what position and at what value at q will the system equilibrium?
Which are the important things or chapters in 11th physics study?
