Answer:
a) interior, b) inside, c) minor
Explanation:
In this exercise you are asked to select the correct words so that the statements have been correct
Electric charges always repel each other when they are of the same sign, in conductors this has the consequence that charges accumulate on the surface and the interior remains without electric charges. with this we analyze the statements
a) interior
b) inside
c) minor
therefore the phrase would be:
(a) The net charge is always zero ---INTERIOR--- the surface of an isolated conductor.
(b) The electric field is always zero ---INSIDE--- a perfect conductor.
(c) The charge density on the surface of an isolated, charged conductor is highest where the surface is ---MINOR---to)
Answer:
0 N/C
Explanation:
Parameters given:
The distance between 
and 
is
Electric field is given as
r = 15/2 = 7.5cm = 0.075m
The electric field at their midpoint due to is:
= 
The electric field at the midpoint due to is:
= 
The net electric field will be:
E = +
E = 
+ 
E = 0 N/C
It stops cause of gravitaional pull
Answer:
(a) 2400N
(b) Yes
Explanation:
(a) Mass (m) = 1.5kg, initial speed (v) = 4m/s, time (t) = 2.5milliseconds = 2.5/1000 = 0.0025seconds
F = mv/t = (1.5×4)/0.0025 = 6/0.0025 = 2400N
(b) The force would be different because the mass of the two hands and forearms is 3kg (2 × 1.5kg = 3kg)
