Answer:
The electron tends to go to the region of 4. higher electric potential.
Explanation:
When a charged particle is immersed in an electric field, it experiences a force given by
where
q is the charge of the particle
E is the electric field
The direction of the force depends on the sign of the charge. In particular:
- The force and the electric field have the same direction if the charge is positive
- The force and the electric field have opposite directions if the charge is negative
Therefore, an electron (negative charge) moves in the direction opposite to the electric field lines.
However, electric field lines go from points at higher potential to points at lower potential: so, electrons move from regions at lower potential to regions of higher potential.
Therefore, the correct answer is
The electron tends to go to the region of 4. higher electric potential.
Answer:
PART A)
L = 97.4 dB
PART B)
PART C)
L = 67.9 dB
Explanation:
PART A)
level of sound is given as
now we have
PART B)
Since source is a spherical source
so here the intensity of sound is inversely depends on the square of the distance from the source
PART C)
level of sound is given as
now we have
