birajpandey182: Ans is

tauseefwatto0: k/r=m(v^2) Energy=2k/r

birajpandey182: According to question,Mv2R=AR2v2=AMRK.E.=12Mv2K.E.=A2R .................. (1)Force acting on the particle is conservative in nature. HenceF=−dUdrdU=−FdRP.E, U=−∫R∞FdRU=∫R∞AR2dRU=−ARTotal energy, E=K.E+P.EE=A2R−AR=−A2R

bornikadas73: okay sorry

tauseefwatto0: sorry

bornikadas73: why sorry

tauseefwatto0: total energy =k. E. +P. E=k/2r+0=k/2r

bornikadas73: oo

bornikadas73: okay

bornikadas73: bye
