Answer:
Newtons
Explanation:
Magnitude of charge on the electron = q =
Coulombs
The negative sign in the question statement indicates that the charge is negative.
Magnitude of Electric Field experienced by the electron = E =
Newtons/Coulomb
Magnitude of Force on the electron = F = ?
The relation between the charge, electric field and the force on the charge because of electric field is given by:

From here we can write:
F = qE
Using the values, we get:

Thus, the magnitude of the electric force experience by the electron would be
Newtons
Answer:
a) The trajectory will be a helical path.
b) θ = 2*π rad
Explanation:
a) Since the initial velocity of the particle has a component parallel (x-component) to the magnetic field B
, the trajectory will be a helical path.
b) Given
t = 2*π*m/(q*B)
We can use the equation
θ = ω*Δt
where
θ is the angular displacement
ω is the angular speed, which is obtained as follows:
ω = q*B/m
then we have
θ = (q*B/m)*2*π*m/(q*B)
⇒ θ = 2*π rad
Answer:
T=Lnsin
Please check the attached
Explanation:
The torque can simply be calculated by multiplying the length of the rod by the perpendicular force n as shown in the attached figure.
Note that sin90=1
T=Lsin

T=Lnsin
Answer:
A (2066,6 N)
Explanation:
Use the Work formula
62.000J = F . 30
62.000/30 = 2066,6 N
The amout of time it took to move the rock doesn´t matter at all.
It is called a distraction variable, We don´t need it to solve the problem it is there just to confuse.
