Here are the solutions to the problems: a) Step 1: Read the value from the spring balance in Fig 3.1. The spring balance has major markings at 0 N, 5 N, and 10 N. Between 0 N and 5 N, there are 4 smaller tick marks, dividing the 5 N range into 5 equal intervals. Therefore, each small interval represents 5 N5 = 1 N. The pointer is at the second tick mark after 0 N. The weight of the wooden block is 0 N + 2 × 1 N = 2 N. The weight of the wooden block is 2 N. b) Step 1: State the formula for weight. The relationship between weight (W), mass (m), and acceleration due to gravity (g) is given by: W = mg Step 2: Rearrange the formula to solve for mass. m = (W)/(g) Step 3: Substitute the given values and calculate the mass. Given W = 2 N (from part a) and g = 10 N/kg. m = 2 N10 N/kg m = 0.2 kg The mass of the wooden block is 0.2 kg. c) Step 1: State the formula for gravitational potential energy. The gravitational potential energy (GPE) gained is given by: GPE = mgh Step 2: Substitute the values and calculate the gravitational potential energy. Given m = 0.2 kg (from part b), g = 10 N/kg, and h = 10 m. GPE = (0.2 kg) × (10 N/kg) × (10 m) GPE = 2 N × 10 m GPE = 20 J The gravitational potential energy gained by the block is 20 J.
