Alright — let's do this. The moment of a force about a point (also called torque) is calculated as the product of the force and the perpendicular distance from the point to the line of action of the force. Moment = Force × Distance Step 1: Calculate the moment due to the 50 N force about point O. The force is F_1 = 50 N. The perpendicular distance from point O to the 50 N force is d_1 = 3 m. Moment_50 N = F_1 × d_1 = 50 N × 3 m Moment_50 N = 150 Nm Step 2: Calculate the moment due to the 80 N force about point O. The force is F_2 = 80 N. The perpendicular distance from point O to the 80 N force is d_2 = 4 m. Moment_80 N = F_2 × d_2 = 80 N × 4 m Moment_80 N = 320 Nm Step 3: Compare the calculated moments with the given options. Moment of 50 N is 150 Nm. Moment of 80 N is 320 Nm. This matches option (C). The final answer is C) moment of 50 N is 150 Nm and 80 N is 320 Nm. Drop the next question.
