Answer:
a) x = 0.200 m
b)E = 3.84*10^{-4} N/C
Explanation:
DISTANCE BETWEEN BOTH POINT CHARGE = 0.5 m
by relation for electric field we have following relation
according to question E = 0
FROM FIGURE
x is the distance from left point charge where electric field is zero
solving for x we get
x = 0.200 m
b)electric field at half way mean x =0.25
E = 3.84*10^{-4} N/C
Answer:
The velocity of water at the bottom,
Given:
Height of water in the tank, h = 12.8 m
Gauge pressure of water,
Solution:
Now,
Atmospheric pressue,
At the top, the absolute pressure,
Now, the pressure at the bottom will be equal to the atmopheric pressure,
The velocity at the top, , l;et the bottom velocity, be
.
Now, by Bernoulli's eqn:
where
Density of sea water,
