A) 1150 N
B) 1250 N
C) 1300 N
D) 1420 N
Correct Answer: B
Solution :
Required force \[F=\mu {{\,}_{AB}}\,{{R}_{A}}+{{\mu }_{BS}}\,{{R}_{B}}\] \[= \,0.25 \times 100g +\frac{1}{3}-\,\,\left( 100 + 200 \right)g\] \[=\,\,\,25g\,\,+\,\,100g\] \[=\,\,\,125g =125\times 10\] \[=\,\,\,1250\,\,N\]You need to login to perform this action.
