An object is spun around in circular motion such that its frequency is 12 Hz.
1 answer:
Explanation:
Given parameters:
Frequency = 12Hz
Unknown:
a. Period of its rotation
b. Time required to complete 86 rotations
Solution:
Frequency is the number of times of rotation per unit of time.
Frequency =
Period is the opposite of frequency;
Period = = 0.083s
b. Time for 86 rotations;
Since frequency =
n is the number of rotation
t is the time
t = =
= 7.2s

Answer:
E = 1.655 x 10⁷ N/C towards the filament
Explanation:
Electric field due to a line charge is given by the expression
E = [/tex]
where λ is linear charge density of line charge , r is distance of given point from line charge and ε₀ is a constant called permittivity and whose value is
8.85 x 10⁻¹².
Putting the given values in the equation given above
E =
E = 1.655 x 10⁷ N/C
