" The graph between "sqrt(E_(k))" and "1/p" is (Ek=kinetic energy "p" = momentum) "

The graph betwee sqrt(E) and (1)/(p) is (E=kinetic energy and p= momentum)

The graph betwee sqrt(E) and (1)/(p) is (E=kinetic energy and p= momentum)

The graph between linear monentum (p) and Kinetic energy (k) is best represented by

If E is a rotational kinetic energy then angular momentum is

Which of the following graphs represents the graphical relation between momentum (p) and kinetic energy (K) for a body in motion?

Relation between kinetic energy and momentum Let us consider a body of mass 'm' having a velocity 'v', then momentum of the body P = mass xx velocity P = m xx v rArr v = (P)/(m) " "...(1) From definition, kinetic energy (K.E) of the body K.E = (1)/(2) mv^(2)" "...(2) Now putting the value of (1) in (2) we have K.E = (1)/(2)m ((P)/(m))^(2) K.E. = (1)/(2)m (P^(2))/(m^(2)) = (1)/(2) (P^(2))/(m) = (P^(2))/(2m)" "...(3) Thus we can write P^(2) = 2m xx K.E rArr P = sqrt(2m xx K.E) Thus momentum = sqrt(2 xx "mass" xx "kinetic energy") What will be the momentum of a body of mass 100 g having kinetic energy of 20 J ?

In the experiment on photoelectric effect, the graph between E_K(max) and v is found to be a straight line as sshoen in fig. The threshold frequency and Planck's constant according to this graph are

(a) A proton is moving at a speed much less than the speed of light. It has kinetic energy K_1 and momentum p_1 . If the momentum of the proton is doubled, so p_2 = 2 p_1 , how is its new kinetic energy K_2 related to K-1 ? (b)A photon with energy E_1 has momentum p_1 . if another photon has momentum p_2 that is twice p_1 , how is the energy E_2 of the second photon related to E_1 ?
