Explanation:
Answer:
x = 0.47 m
Explanation:
PS = ½kx²
x = √(2PS/k) = √(2(49)/450)) = 0.466666...
Answer:

Explanation:
As we know that the oil drop experiment tells us the balancing the gravitational force by electrostatic force.
So ,
Electrostatic force = Gravitational force
qE=mg
Here , q is charge , E is electric field , m is mass and g is gravity.
so,

Insert values from question,

or

This is the required value of electric field.
Answer:
Magnetic force, 
Explanation:
It is given that,
Speed of electron, v = 16748.76 m/s
Magnetic field, B = 0.0177 T
Angle between velocity vector and the magnetic field vector are make an angle of 59.24°. Magnetic force is given by :



So, the magnetic force on the electron is
. Hence, this is the required solution.
