info@snapandsolve.comAnswer: The tension in the upper string is 39.2 N.
Explanation: The tension in the upper string must support the weight of both blocks. Each block has a mass of 2 kg, so the total mass is 4 kg. The force due to gravity is calculated as F = m * g, where g = 9.8 m/s². Thus, F = 4 kg * 9.8 m/s² = 39.2 N.
