A particle with positive charge \( 10^{-3} \, \text{C} \) and mass \( 0.2 \, \text{kg} \) is thrown upwards from the ground at an angle \( 45^\circ \) with the horizontal with a speed of 5 m/s. The projectile moves through a horizontal electric field of 10 V/m, which is in the same direction as the horizontal component of the initial velocity of the particle. The acceleration due to gravity is \( 10 \, \text{m/s}^2 \). The range is .............. m (Round off to three decimal places).
