Three point charges have equal magnitudes, two being positive and one negative. these charges are fixed to the corners of an equilateral triangle, as the drawing shows. the magnitude of each of the charges is 4.5 μc, and the lengths of the sides of the triangle are 1.0 cm. calculate the magnitude of the net force that each charge experiences.

Explanation:

Given

magnitude of charge=4.5\nu C

length of side of triangle=1 cm

There are two Positive charge and one negative charge

So net Force on negative charge is

sum of

where =force exerted by first positive charge on negative charge

=force exerted by second positive charge on negative charge

Two are at an angle of 60 (as it is placed at a corner of equilateral triangle)

Force Experienced by a positive charge will be of attractive and repulsive in nature

Two Forces are at an angle of 120 therefore

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
