A)
B)
C)
D)
Correct Answer: B
Solution :
From Einsteins photoelectric equation, the kinetic energy (KE) of electrons is KE = hv - W ? (i) where W is work function, h the Plancks constant and v the frequency of light Also, equation of straight line is \[y=mx+c\] ... (ii) where m is slope, c the constant. Comparing Eqs. (i) and (ii), we get that graph of E versus v is a straight line of positive slope, cutting the energy axis towards negative.You need to login to perform this action.
