A) \[45.2\times {{10}^{-4}}\text{dyne}\]
B) \[101.73\times {{10}^{-5}}\text{dyne}\]
C) \[16.95\times {{10}^{-4}}\text{dyne}\]
D) \[16.95\times {{10}^{-5}}\text{dyne}\]
Correct Answer: A
Solution :
[a] \[F=6\,\pi \,\eta \,r\,v\] \[=6\times 3.14\times (8\times {{10}^{-5}})\times 0.03\times 100\] \[=4.52\times {{10}^{-3}}\,dyne\]You need to login to perform this action.
