What is Photoelectric effect?

when a photon strikes a meral surface it gives up its energy to electron
part pf thos energy is used up by the electrons to escape from the metal,the remaining imparts the kinetic energy to the photoelectron .if the incident radiation has frequency v then its photons have energy hv u
from the conservation of energy principle
hv=W+1/2mu2
thos is photoelectric effect.
thanks and regards

The photoelectric effect is the observation that many metals emit electrons when light shines upon them. Electrons emitted in this manner may be called photoelectrons.

. Because of the rotation of the earth, a plumb bob may not hang exactly along the direction of
the earth’s gravitational pull (its weight) but deviates slightly from this direction. Calculate the
deviation (a) at 40 latitude, (b) at the poles, and (c) at the equator

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
