Answer:
The electric field dE due to charge dQ is given as:
dE = (KdQ/r) * r^.
r^ is vector position
r^ = sqrt(x2 + a2). Pythagoras theorem.
K is electrostatic constant. K = 1/4πe(0)
There should be 30 cars, but I’m not sure
Answer:
The value of x is -9, 3/4 and 3.
Step-by-step explanation:
In order to find the value of x, tou have to let f(x) equals to 0 :
Let f(x) = 0,
(x-3)(x+9)(4x-3) = 0
x - 3 = 0
x = 3
x + 9 = 0
x = -9
4x - 3 = 0
4x = 3
x = 3/4
