Apositive point charge (q = +8.65 x 10-8 c) is surrounded by an equipotential surface a, which has a radius of ra = 2.97 m. a positive test charge (q0 = +4.56 x 10-11 c) moves from surface a to another equipotential surface b, which has a radius rb. the work done by the electric force as the test charge moves from surface a to surface b is wab = -6.95 x 10-9 j. find rb.

Explanation:

As we know that work done by electric force is given as

so here we know that charge is moving from

to another position

so we will have

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.
