Respuesta :
The correct option is (D). The strength of electric field depends on the amount of charge that produces the field as well as the distance from the charge.
Further Explanation:
The electric field intensity at a point is the measure of the force exerted by a charge particle on another charge particle in the particular area of its strength.
The electric field intensity at a distance [tex]d[/tex] due to a static charge having charge [tex]q[/tex] is directly proportional to the amount of charge and inversely proportional to the square of the distance between them.
The Electric field intensity due to a charge is given as:
[tex]E = \dfrac{1}{{4\pi {\varepsilon _0}}}\frac{q}{{{r^2}}}[/tex]
Here, [tex]E[/tex] is the electric field intensity, [tex]q[/tex] is the amount of charge and [tex]r[/tex] is the distance of the charge from the point.
The above expression of electric field shows that the electric field intensity at a point depends on the amount of charge as well as the distance of the point from the charge.
Thus, the correct option is (D). The strength of electric field depends on the amount of charge that produces the field as well as the distance from the charge.

Answer:
correct option is B. may impede other vehicles on the road that are traveling at normal and safe speeds
Explanation:
solution
we know that driving very slow and very fast than the traffic flow speed is also danger and unsafe
so it is important point that when we driving or riding on road so be cautious of those people who is around you and not being unsafe on road
and vehicles riding or driving with same speed and when suddenly they get close to that extremely slow vehicle
it is easy occurrence for the accident on road
so that why it is very important to keep the speed right in between vehicles
so always be normal and safe speeds are not more than the posted limit and can be much less in bad conditions
so we can say correct option is B
