A particle of mass 9 kg and charge 100C is projected with a speed of 10 m s at an angle 45 above the horizontal After travelling a horizontal distance of 0 5 m It enters into a region where in addition to gravity a uniform static horizontal electric field also exists Boundary of the region is vertical If after some time the particle returns to its original position then find the magnitude of electric field in newton columb
