A) 0.336 N
B) 0.294 N
C) 683N
D) 0.392 N
Correct Answer: A
Solution :
Referring figure, \[0.04g-T=0.04a\] ? (i) and \[T-0.03g=0.03a\] ? (ii) \[\therefore \] \[0.04g-(0.03a+0.03g)=0.04a\] \[\Rightarrow \] \[a=1.4\] \[\therefore \] \[T=0.03\times 1.4+0.03\times 9.8\] \[=\mathbf{0}\mathbf{.336}\,\,\mathbf{N}\]You need to login to perform this action.
