Answer:
I think it's 10 or 10.5 not sure
Step-by-step explanation:
B. is reasonable because 9.2×4.8 = 44.16
The perimeter of the triangle with those given lengths is
The formula is E= kQ/ d^2
k is 9x10^9
i changed 15 cm to 0.15 m
=> 9x10^9 x 12 OVER (0.15)^2
the answer is 4.8x10^12 N/C
but this is the electric field.
to find electric field STRENGTH, it’s E= F/q and you did not give a value for the force
