A) \[19.6\times {{10}^{-8}}N{{C}^{-1}}\]
B) \[20\times {{10}^{-6}}N{{C}^{-1}}\]
C) \[19.6\times {{10}^{8}}N{{C}^{-1}}\]
D) \[20\times {{10}^{6}}N{{C}^{-1}}\]
Correct Answer: C
Solution :
(c) \[19.6\times {{10}^{-8}}N{{C}^{-1}}\] Here, \[m=3.2\times {{10}^{-27}}kg,\]\[e=1.6\times {{10}^{-19}}C\], \[g=9.8\,m{{s}^{-2}}\] As \[E=\frac{F}{q}=\frac{mg}{e}=\frac{3.2\times {{10}^{-27}}}{1.6\times {{10}^{-19}}}=19.6\times {{10}^{-8}}N{{C}^{-1}}\]You need to login to perform this action.
