Two blocks A and B of the same mass are ...

Two blocks A and B of the same mass are joined by a light string and placed on a horizontal surface. An external horizontal force P acts on A. The tension in the string is T. The forces of static friction acting on A and B are `F_(1)` and `F_(2)` respectively. The limiting value of `F_(1)` and `F_(2)` is `F_(0)`. As P is gradually increased.
