1. An electrostatic field line is the path of a positively charged particle in an electric field.Electric field is always continuous(directed from higher to lower potential) and exist at all points around a charge distribution. Hence an electrostatic field line is a continuous curve and cannot have sudden breaks.

2. When a proton is placed in an uniform electric field ,the proton will tend to move along the positive X- axis in the direction of electric field.
