Answer:
The magnitude of the electric field is 8.47 N/C
Explanation:
Given;
uniform charge density, λ = 100 nC/m³
inner radii of the cylinder, r = 1.0 mm and 3.0 mm
distance from the symmetry axis, R = 2.0 mm
Area = 2πrl
Area =2π(2 x 10⁻)l
Volume = A x d
d = Volume / Area
the magnitude of the electric field
Therefore, the magnitude of the electric field is 8.47 N/C
Answer:
Explanation:
Answer:
158.82 rad/s
Explanation:
radius of tyre, r = 34 cm = 0.34 m
tangential speed, v = 54 m/s
Let the angular speed of the pebble is ω.
The relation between the tangential speed and the angular speed is
v = r x ω
where, r is the radius and ω be the angular speed.
54 = 0.34 x ω
ω = 158.82 rad/s
Thus, the angular speed of the pebble is 158.82 rad/s.
One is for far distance the other is for close range
