Answer:
I dont really know much but i know that it swallow anything it comes across in space.
Answer:
Hence the answer is E inside 
.
Explanation:
E inside
so if r1 will be the same then
E 
proportional to 1/R3
so if R become 2R
E becomes 1/8 of the initial electric field.
A and c
do not complete the circuit there is no battery on a and paper dose not conduct electricity
Answer:
25m/sec
Explanation:
Speed of car in first 15 minutes = 40 km/h
Distance covered = speed × Time taken
60 minutes = 1 hour
15 minutes =
60
15
hour
Distance covered = 240×
60
15
=10km
Speed of car in next 15 minutes = 60 km/h
Distance covered = 60×
60
15
=15km
∴ Total distance covered = (10+15)km = 25 km
<span>The relationship between the electric field strength at a point and its distance from the source charge is inversely proportional. As the electric field strength increases the charges are more closer to each other which means the distance between the is smaller. It is seen by the equation:
E = </span><span>(1/4*pi*epsilon0) (Q/r^2)</span>
