A) \[19.091\times {{10}^{-31}}kg\]
B) \[11.5830\times {{10}^{-31}}kg\]
C) \[6.9091\times {{10}^{-31}}kg\]
D) \[9.1091\times {{10}^{-31}}kg\]
Correct Answer: D
Solution :
Mass of electron\[=\frac{e}{e/m}\] \[=\frac{1.60206\times {{10}^{-19}}}{1.75875\times {{10}^{11}}}=9.1091\times {{10}^{-31}}\,kg.\] Hence, the correct option is [d].You need to login to perform this action.
