B

(A) \rightarrow (iii),(B) \rightarrow (i), (C) \rightarrow (ii), (D) \rightarrow (iv)

C

(A) \rightarrow (ii), (B) \rightarrow (iii), (C) \rightarrow (iv), (D) \rightarrow (i)

D

(A) \rightarrow (i), (B)\rightarrow (iii), (C)\rightarrow (ii), (D) \rightarrow (iv)

Answer

(A) \rightarrow (iii),(B) \rightarrow (i), (C) \rightarrow (ii), (D) \rightarrow (iv)

Explanation

Solution

: Mass of electron=9.1×1031kg= 9.1 \times 10^{- 31}kg

Mass of proton = 1.673×1027kg1.673 \times 10^{- 27}kg

Charge on an electron =1.602×1019C= - 1.602 \times 10^{- 19}C

e/m for an electron=1.76×108C/g= 1.76 \times 10^{8}C/g
