What is the force felt by the electrons and the nuclei in the rod when the external field described in the problem introduction is applied? (ignore internal fields in the rod for the moment.)a) both electrons and nuclei experience a force to the right.
b) the nuclei experience a force to the right and the electrons experience a force to the left.
c) the electrons experience a force to the left but the nuclei experience no force.
d) the electrons experience no force but the nuclei experience a force to the right.

(B). nuclie experiences a force to the right and electron experiences a force to the left.

Explanation: The nuclie is positively charged and so it will experience a force in the same direction as the direction of the Electric Field {in this case to the right}

On the otherhand, the electrons which are negatively charge will experience a force in opposite direction to that experienced by the nuclie which is positively charged. So the electron experiences a force to the left.

I believe this is clear.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
