    sir my ques. is In annihilation concept of chp. electrostatics why e- + e+ -> 2gamma ray photon,

  2. physicsmaster

    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

    1. admin

      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)

  7. devender sharma

    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

    1. admin

      yes; T= m(a+g) while climbing up

    is electric field intensity,,,,and electric field strength is same

  9. sachin

    relation between electrivc field intensity and flux density in case of sphere containing charge
    a) d=e/e0
    b) d=q/e0
    c) d=e.e0
    d) d=none
