Mass (kg) - 0.08
Mass of weight hanger + slotted weights - 210 g/ 0.21kg
Tension 1 (N) - ??
Acceleration (m/s2) - ??
Tension 2 (N) - ??

C. )
Bag C + 2 stones
Mass (kg) - 0.074
Mass of weight hanger + slotted weights - 210 g/ 0.21kg
Tension 1 (N) - ??
Acceleration (m/s2) - ??
Tension 2 (N) - ??
Tension 3 (N) - ??

======================

if you please write it in details so I can do trial 2 and 3 on my own then

======================

TRIAL 2 - Mass of weight hanger + slotted weights = 0.26kg

Bag A - 6 stones - 0.058g; Tension 1 = ?, acceleration = ?
Bag B - 4 stones - 0.090g; Tension 1 = ?, acceleration = ?, Tension 2 = ?
Bag C - 2 stones - 0.081g; Tension 1 = ?, acceleration = ?, Tension 2 = ?, Tension 3 = ?

======================

TRIAL 3 - Mass of weight hanger + slotted weights = 0.36kg

Bag A - 6 stones - 0.078g; Tension 1 = ?, acceleration = ?
Bag B - 4 stones - 0.159g; Tension 1 = ?, acceleration = ?, Tension 2 = ?
Bag C - 2 stones - 0.091g; Tension 1 = ?, acceleration = ?, Tension 2 = ?, Tension 3 = ?


======================

FORMULAS

F=ma
T1 - Tabc = (Mabc)a
T2= ?
T3= ?
T2- Fbc = (Mbc)a
T3 - Fc = (Mc)a
