Two blocks of masses 2 kg and 4 kg are attached by an inextensible light string as shown in the figure. If a force of 120 N pulls the blocks vertically upward, the tension in the string is (take \(g = 10 \text{ ms}^{-2}\))
Show Hint
For connected masses, always find the acceleration of the whole system first. Then, look at the block that has fewer forces acting on it (usually the bottom one) to solve for tension quickly.
