Answer
a) Electron is moving toward right and brought to rest it means that force should be in opposite direction of motion electron.
We know F = qE here q = -e so, Force will be F = - eE.
Force on electron will be acting in opposite direction so, the electric field direction will be towards Right.
b) we know,
Force on electron = Electric force
m a = eE
using equation of motion
v² = u² + 2 a s
0 = (5.5 x 10⁵)² - 2 x a x 0.05
e = 1.6 x 10⁻¹⁹ C
mass of electron, m = 9.1.09 x 10⁻³¹ Kg
now,
E = 17.22 N/C
hence, strength of electric field is equal to E = 17.22 N/C
Answer:
C.
Explanation:
The induced current is related to the rate of change of the magnetic flux in a loop wired, so adding a strong magnet will increase the magnetic flux, and if we increase the spinning we'll increase the change of rate, so both induced a bigger current, so b,c, and d are also correct, but c will show better results.
Answer:
Explanation:
Given
Current in the conductor
maximum Force
If Poles Faces are 55.5 cm in diameter i.e. Length
Force experience by a current carrying conductor is given by
where
thus Strength of Magnetic Field is 0.263 T
