Answer:
To your left
Explanation:
The direction of the force exerted on charged particle due to a magnetic field is given by the right-hand-rule, where:
- The index finger indicates the direction of motion of the electron
- the middle finger gives the direction of the magnetic field
- the thumb gives the direction of the force if the particle is positively charged - otherwise, the direction is reversed
in this case, we have an electron (so, a negatively charged particle):
- The direction of motion (index finger) is horizontal, toward you
- The electron begins to curve upward as it enters the field, so this means that the force exerted on the electrons is upward --> the thumb must point downward (because the electron is negatively charged)
- The index finger gives us the direction of the magnetic field: therefore, to your left.
Explanation:
In induction, what charge does a neutral substance gain compared to the object brought near it?
The neutral object gains the same type of charge as the object that touched it because the electrons move from one object to the other (Figure 10.16). Induction is the movement of electrons within a substance caused by a nearby charged object, without direct contact between the substance and the object.
Answer:
Explanation:
Given that,
Width of a one dimensional potential box, 
The energy of a particle in one dimensional box is given by :
h = Planck's constant
m = the mass of the proton
For minimum kinetic energy, n = 1
So, the minimum kinetic energy of the neutron is 
. Hence, this is the required solution.
Answer:
Friction can be increased the longer two objects are rubbed together, since the longer they are rubbed is the more heat produced.
