Final answer:The tension in the string of the conical pendulum at the highest point of its motion is equal to the weight of the 500g ball, which is 4.9 N.Explanation:The question involves the concept of a conical pendulum, which is a physics topic. Considering a 500g (0.5 kg) ball attached to a 1m string moving in a horizontal circle, we can calculate the tension at the highest point. For a conical pendulum, the tension in the string at the highest point should be equal to the weight of the mass, since there are no other forces acting in the vertical direction. The weight of the 500g ball (W) is calculated using the equation for weight (W = mg), where m is mass, g is acceleration due to gravity (9.8 m/s2).Using the values:W = 0.5 kg x 9.8 m/s2W = 4.9 NTherefore, the tension in the string when the ball is at the highest point of its motion is 4.9 N, making option (b) correct....
