It can easily be found by simple plane and direction condition. Since the slip direction must lie in the slip plane so if (hkl)- slip plane and [uvw]- slip direction then by direction will lie in plane if hu+kv+lw=0 . So by que, B option is the only system which didn't satisfy this. That means it doRead more

So by que,
B option is the only system which didn’t satisfy this. That means it doesn’t lie in slip plane and hance not a slip system.
See lessCorrect answer is option B. @Rohit.km described it best. Thank you. Some peripheral lines related to this topic: (hkl) [uvw] are said to be slip system hu + kv + lw = 0
Correct answer is option B. Rohit jha.km described it best. Thank you.
Some peripheral lines related to this topic:
hu + kv + lw = 0

See lessFor a valid slip system there is a condition given below; slip direction * slip plane = 0 so 1*0+1*1+1**1 = 2 which is not equal to zero hence B is correct
For a valid slip system there is a condition given below;
slip direction * slip plane = 0
so 1*0+1*1+1**1 = 2 which is not equal to zero
See lesshence B is correct
