8 A particle of mass m and charge q projected with a speed u at an angl e above the horizontal after travelling a horizontal distance xo enters region where in addition to gravity a uniform static horizontal electri field also exists Boundary of this region is vertical If after some time the particle returns to the point of projection find magnitude of th electric field and time of flight of the particle Acceleration of free fall g and influence of the air is to be neglected
