(a) An electrostatic field line is a continuous curve because a charge experiences a continuous force when traced in an electrostatic field. The field line cannot have sudden breaks because the charge moves continuously and does not jump from one point to the other.
(b) If two field lines cross each other at a point, then electric field intensity will show two directions at that point. This is not possible. Hence, two field lines never cross each other.

IMPULSE When a large force is applied on a body for a very short interval of time, then the product of force and tire interval is known as impulse. \[ \mathrm{d} \overline{\mathrm{t}}=\hat{\mathrm{F}} \mathrm{d} \mathrm{t}=\mathrm{d} \overrightarrow{\mathrm{p}} \quad\left[\because \frac{\mathrm{d} \overrightarrow{\mathrm{p}}}{\mathrm{dt}}=\hat{\mathrm{F}}\right] \] Units of impulse or . Dimensions of impulse Case -I : If this force is working from time to , then integrating the above equation, we get - Case-II : If a constant or average force acts on body, then :- \[ \begin{array}{l} \overrightarrow{\mathrm{I}}=\overrightarrow{\mathrm{F}}_{\text {avg }}[\mathrm{t}]_{1_{1}}^{t_{2}}=[\overline{\mathrm{p}}]_{p_{1}}^{\vec{p}_{2}} \quad \Rightarrow \quad \overrightarrow{\mathrm{I}}=\overrightarrow{\mathrm{F}}_{\text {avg }}\left(\mathrm{t}_{2}-\mathrm{t}_{1}\right)=\left(\overrightarrow{\mathrm{p}}_{2}-\overrightarrow{\mathrm{p}}_{1}\right) \\ \overrightarrow{\mathrm{i}}=\overrightarrow{\mathrm{F}}_{\mathrm{avg}} \Delta \mathrm{t}=\Delta \overrightarrow{\mathrm{p}} \\ \end{array} \]
