Express your answer using two signilicant figures Constants A 58 kg student stands on a very light, rigid board that rests on a bathroom scale at each end, as shown in Figure 1). Ret Submit 1 of 1 Figure Incorrect Try Again; 5 attempts remaining Part What is the reading on the right scale? Express your answer using two significant figures 1.5 m 2.0 m

Explanation / Answer

Here ,

m = 54 Kg

x1 = 1.5 m

L = 2 m

let the reading on the left scale is FL

reading on the right scale is RL

part A) balancing the torque about the right end

FL * (2) - 58 * 9.8 * 0.50 = 0

solving for FL

FL = 142.1 N

the lead on the left scale is 142.1 N

part B)

balancing the vertical force

FL + FR = weight

142.1 + FR = 54 * 9.8

FR = 387 N

the reading on the right scale is 387 N
