A) +1
B) -2
C) +2
D) -1
Correct Answer: C
Solution :
[c] For \[{{M}_{1}}:V=-\,60,{{m}_{1}}=-2\] For \[{{M}_{1}}:u=+20,F=10\] \[\frac{1}{V}=\frac{1}{20}=\frac{1}{10}\Rightarrow V=20\text{ }\therefore {{M}_{2}}=-\frac{20}{20}=-1\] \[\therefore M={{m}_{1}}\times {{m}_{2}}=+2\]You need to login to perform this action.
