Answer:
475 N/C
Explanation:
As we know that, the electric field in parallel plate capacitor is same (constant) throughout. And is potential gradient.
So, Electric field is given by
Electric field = potential gradient
Here, the potential change is 3.8V and the distance from negative plate to positive plate is 1.6 cm. The potential from negative plate to the center is (1.6/2)cm i.e., 0.8 cm.
But we have to take distance in SI units So, distance=
So, Electric field is
So, electric field is 475 Volts per meter.
Note : Also we can say 475 Newtons per coulomb
Penelope is Your Answer!!! :)
F = qE = mg
E = mg/q = 0.017*9.81('-3.1x10^-6) = 5.38x10^4 = -53,800 N/C
E' = 0.5E = -26,900N/C
2q -mg= ma, Answer is 9.81 m/s^2 and it's positive because the force is upward.
