To calculate the force acting on a given body when moving in a circle, we will use the formula: F = m * ac = m * V ^ 2 / R.
Values of variables: m – body weight (m = 20 g = 0.02 kg); V – constant speed of movement (V = 90 m / s); R is the radius of the circle (R = 0.2 m).
Calculation: F = m * V ^ 2 / R = 0.02 * 90 ^ 2 / 0.2 = 810 N.
Answer: A body moving in a circle is affected by a force of 810 N.
