Two blocks `A` and `B` are being accelerated by forces shown in figure with accelerations `veca_(1)` and `veca_(2)` respectively. The value of `|veca_(1)-veca_(2)|`
Two rough blocks A and B ,A placed over B move with acceleration veca_(A) and veca_(B) veclocities vecv(A) and vecv_(B) by the action of horizontal forces vec(F_(A)) and vec(F_(B)) , respectively. When no friction exsits between the blocks A and B,
If veca and vecb are two non-collinear unit vectors and if |veca_(1) + veca_(2)|=sqrt(3) , then the value of (veca_(1) -veca_(2))(2veca_(1) +veca_(2)) is:
In the system shown in figure, all surfaces are smooth, pulley and strings are massless. Mass of both A and B are equal. The system is released from rest. (a) Find the veca_(A). veca_(B) immediately after the system is released. veca_(A) "and" veca_(B) are accelerations of block A and B respectively. (b) Find veca_(A) immediately after the system is released.
If |veca|=|vecb|=|veca+vecb|=1 then find the value of |veca-vecb|
The equation of the plane contaiing the lines vecr=veca_(1)+lamda vecb and vecr=veca_(2)+muvecb is
It is given that |vecA_(1)|=2,|vecA_(2)|=3 and |vecA_(1)+vecA_(2)|=3 Find the value of (vecA_(1)+vecA_(2)).(2vecA_(1)-3vecA_(2))
Lines vecr = veca_(1) + lambda vecb_(1) and vecr = veca_(2) + svecb_(2) will lie in a Plane if
