Question

Two blocks of masses m and 2m are pkaced one over the other as shown in figure. The coefficient of friction
between m and 2m is u and between 2m and
ground is =
If a horizontal force F is applied on
upper block and T is tension developed in string, then
choose the incorrect alternative.

(A) If F = mg, T = 0
(B) If F = umg, T'= 0
umg
ses 19 F = 2 jumg, T = sung
(D) f F = 3;img, T = 0​
