Answer:
zero
Explanation:
q = 6.4 nC = 6.4 x 1 0^-9 C
d = 16 cm = 0.16 m
r = 16 / 2 = 8 cm = 0.08 m
Electric field at P due to the charge placed at A
Ea = k q / r^2
Ea = ( 9 x 10^9 x 6.4 x 10^-9) / (0.08 x 0.08) Towards right
Ea = 9000 Towards right
Electric field at P due to the charge placed at B
Eb = k q / r^2
Eb = ( 9 x 10^9 x 6.4 x 10^-9) / (0.08 x 0.08) Towards left
Eb = 9000 Towards left
The magnitude of electric field is same but teh direction is opposite, so the resultant electric field at P is zero.
Answer:
electric potential energy=
so the electric potential energy and distance(r) are inversely proportional.
then, the greatest energy occur in the smallest distance b/n the two balloon.
The correct answer for the given question above would be option B. Air flowing from the equator to the poles rises and falls in looping patterns and these patterns are called convection cells. Convection cells<span> is an important process in the formation of landforms and the movement of winds. Hope this answers your question.</span>
Answer:
true
Explanation:
Energy stored in the nuclei of atoms can be used to generate electricity. ... Most of the energy of food is converted to heat.
