My lg is driplikemessiah and I don’t know which one it is but I say go with C
True!!!!!!!!!!!!!!!!!!!!!
Only velocity uses direction of travel in its calculations.
Answer:
The potential difference between the plates is 
Explanation:
Given that,
Distance = 1.4 mm
Electric field strength 
Let the potential difference is V.
We need to calculate the potential difference between the plates
Using formula of electric field


Where, V = potential
d = distance
Put the value into the formula


Hence, The potential difference between the plates is
