Question

choose the incorrect expression of E vector for field to be electrostatic electric field

Answer 1

Answer:

A more useful means of visually representing the vector nature of an electric field is through the use of electric field lines of force. Rather than draw countless vector arrows in the space surrounding a source charge, it is perhaps more useful to draw a pattern of several lines that extend between infinity and the source charge. These pattern of lines, sometimes referred to as electric field lines, point in the direction that a positive test charge would accelerate if placed upon the line. As such, the lines are directed away from positively charged source charges and toward negatively charged source charges. To communicate information about the direction of the field, each line must include an arrowhead that points in the appropriate direction. An electric field line pattern could include an infinite number of lines. Because drawing such large quantities of lines tends to decrease the readability of the patterns, the number of lines is usually limited. The presence of a few lines around a charge is typically sufficient to convey the nature of the electric field in the space surrounding the lines.

Answer 2

Answer:

Explanation:

HELLO DEAR,

Electric Field : The space arround a charge in which its effect can be felt significantly i.e. the area which produces attraction or repulsion force on another charge is called electric field.

Electric Field Lines: Electric field lines are a way of pictorially mapping the electric field intensity around a configuration of charge (s). These lines start from positive charge and end on negative charge .The tangent on these lines at any point gives the direction of field at that point .

l HOPE IT HELP YOU DEAR,

THANKS.
