A particle of charge per unit mass `alpha` is released from origin with a velocity `vecv=v_(0)hati` uniform magnetic field `vecB=-B_(0)hatk`. If the particle passes through `(0,y,0)`, then `y` is equal to

A proton is fired from origin with velocity vecv=v_0hatj+v_0hatk in a uniform magnetic field vecB=B_0hatj .

Choose the correct option: A particle of charge per unit mass alpha is released from origin with a velocity vecv=v_(0)hati in a magnetic field vec(B)=-B_(0)hatk for xle(sqrt(3))/2 (v_(0))/(B_(0)alpha) and vec(B)=0 for xgt(sqrt(3))/2 (v_(0))/(B_(0)alpha) The x -coordinate of the particle at time t((pi)/(3B_(0)alpha)) would be
