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)
11I tried the question, answer toh out of world aa rahe hain [3]. ( am sure the ones am getting are not the answers)
11@ Qwerty,
lallu questions hi ham lallu banate hain aur humari vaat bhi lagate hain [3][3]
11@ Vivek,
tell me the name of the book from where you get this questions, kafi mast question hai [1]
