Four blocks of same mass connected by strings are pulled by a force $$F$$ on a smooth horizontal surface as shown in figure. The tension $$T_1, T_2$$ and $$T_3$$ will be

AIIMS 2017 Physics - Laws of Motion Question 9 English

$$T_1=\frac{1}{4} F, T_2=\frac{3}{2} F, T_3=\frac{1}{4} F$$

$$T_1=\frac{1}{4} F, T_2=\frac{1}{2} F, T_3=\frac{1}{2} F$$

$$T_1=\frac{3}{4} F, T_2=\frac{1}{2} F, T_3=\frac{1}{4} F$$

$$T_1=\frac{3}{4} F, T_2=\frac{1}{2} F, T_3=\frac{1}{2} F$$
