71Sorry Wrong..!!
A. 
Then: (One or more may be correct)
1.) T = 5 N
2.) T = 10 N
3.) T' = 5 N
4.) T' = 0
B.
Weight of sphere = W and a force P is applied on its surface to attain equilibrium (Friction is present). Then
1. Pmin = √3W/2
2. Pmin = (√5-1)W/2
3. When P is minimum, Angle of friction max between sphere and wall is cos -1 (√5-1)/2
4. When P is minimum, Angle of friction max between sphere and wall is tan -1 (√3-1)/(√5-1)

1well thats going to be a big one.....
hint : Assume accln of bodies wrt the body on which it is kept ( this makes the solving process a bit simpler as we know that relative accln betn two bodies in contact along the perpendicular direction is zero)
