The time taken by a photoelectron to come out after the photon strikes is approximately

A

`10^(-4)s`

B

`10^(-10)s`

C

`10^(-16)`

D

`10^(-1) s`

Text Solution

Verified by Experts

The correct Answer is:
B
The photoelectric phenomenon is an instantaneous phenomenon, hence the time taken be an electron to come out of metal is approximately `10^(-10)` sec (found experimentally).

A uniform electric field of magnitude E exists in between two parallel metal plates , as shown in the figure given below. One particle of mass m and charge q is projected along the central line between the plates. Particle just missed to strike upper plate , while coming out of plates. Find : (a)Time taken by the particle to come out of plates. (b)Speed of the particle as it comes out of plates. (c) Angle of deviation suffered by particle. The length of the plates is L and the distance between the plates is d. Ignore gravity .

A particle startsits SHM at t=0 . At a particular instant on its way to extreme position , x= (A)/(2) . Find the time taken by the particle to come back to this point after passing through the extreme position. Hint : t_(1) = time taken to go from x=0 to x= (A)/(2) t_(2) = time taken to go to extreme position and come back to mean position = (T)/(2) Required time = (T)/(2) - t_(1)
