Answer:
5s
Explanation:
-A period is the time it takes to make one full back-and-forth swing.
-A period is calculated as the time taken for a complete swing divided by one cycle:
Hence, the period of the pendulum is 5s
For small deflections, T = 2*pi*sqrt(L / g) where T is period, L is length and g is gravity.
Setting the equations to the same period, 2*pi*sqrt(3.85 / g) = 2*pi*(L / (1/6 * g))
The equation reduces to 3.85 m = 6 * L so L = 0.642 m

Answer:
a) 0.99999 e
b) 1*10^-5 s
c) 3*10^-2 m
Explanation:
Given data:
Electron energy : 50 GeV
assuming the rest mass of an electron = 0.5 MeV/c^2
A) Determine the velocity of each electron
velocity of each electron ( v ) ≈ 0.999 e
B) How much time does it take the electrons to travel the length of the accelerator given that the accelerator = 3km long
Lo = 3 * 10^3 m
T = (3 * 10^3 )/ (0.999 * 3 * 10^8)
= 1 * 10 ^-5
C) How long does the accelerator look form the perspective of the electrons
L = Lo / r = Lo 
hence L = 3 * 10^-2 m
Electrical charges on one or more particles within the field cause the electric field
Each point in space has an electric field associated with it when a charge of any kind is present. The value of E, often known as the electric field strength, electric field intensity, or just the electric field, expresses the strength and direction of the electric field
A region of space surrounding an electrically charged particle or object known as an electric field is one in which an electric charge would experience force. A vector quantity called an electric field can be represented by arrows pointing in the direction of or away from charges. The force per unit charge exerted on a positive test charge that is at rest at a given position is the force per unit charge that is used to define the electric field analytically.
