Answer:
The magnitude and direction of the magnetic field is 93.63 T in negative x direction.
Explanation:
Given;
speed of the electron in positive y direction, v = 2.0 x 10⁵ m/s
magnetic force on the electron, F in negative z direction = 3.0 x 10⁻¹² N
The magnitude of the magnetic force is given by;
F = Qv x B
B = F / Qv
The direction of the magnetic field is is as;
Based on the direction of magnetic force (negative z direction), the charge will be directed into negative y-direction because electron is negatively charged. Thus, the direction of the magnetic field will be in the negative x-direction
Therefore, the magnitude and direction of the magnetic field is 93.63 T in negative x direction.
Answer:
Explanation:
According to the Coulomb's law, the magnitude of the electrostatic force between two static point charges and
, separated by a distance
, is given by
where k is the Coulomb's constant.
Initially,
The negative sign is taken with force F because the force is attractive.
Therefore, the initial electrostatic force between the charges is given by
Now, the objects are then brought into contact, so the net charge is shared equally, and then they are returned to their initial positions.
The force is now repulsive, therefore,
The new charges on the two objects are
The new force is given by
