A particle of charge q,mass m ,moving with velocity vo(i+j) enters a uniform magnetic field Bo(i)? 1.find the displacement of particle after time t = πm/qB.{ ans= (mvo/qB)(πi-2k)
2.find displacement of particle after time t= 2πm/qB {ans=(2πmvo/qB)(i)}
3. find displacement of particle for any arbitrary time t. {ans= vot i+ (mvo/qB)sin(qBt/m) j + mvo/qB(cos(qBt/m)-1)k
pls explain how to do ???
