A source charge generates an electric field of 1236 N/C at a distance of 4 m. What is the magnitude of the source charge? A. 2.2 ɥC
B. 680 ɥC
C. 2.2 C
D. 680 C

can someone explain this in detail because im having a hard time understanding these type questions...thank you!!

A. 2.2 ɥC

Explanation:

Given;

electric field strength, E = 1236 N/C

distance of the source charge, r = 4 m

Electric field strength is calculated as;

where;

Q is the magnitude of the source charge

k is Coulomb's constant = 9 x 10⁹ Nm²/C²

Therefore, the correct option is A. 2.2 ɥC

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated

don't remove my answer im trying my best to answer them

explanation:

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
