Question

B. the acceleration should be on the horizontal axis and the mass ratio should be on the vertical axis

A. the acceleration should be on the vertical axis and the mass ratio should be on the horizontal axis

B. the acceleration should be on the horizontal axis and the mass ratio should be on the vertical axis

3. A glider with mass is pulled on an air track by a string attached to a falling mass as shown in Figure 7.1 in the lab manual.

Which one of the following is the correctly scaled free body diagram for the falling mass ?

Choose one answer. (a) (b) (c) (d) (e) 1. Newton's 2nd Law applied to the system gives a = ( m/M + m) g . What are the SI units of the mass ratio ( m/M + m) ? Choose one answer. a. kg b. kg^2 c. no units 2. graph will be made using the values of acceleration and the mass ratio . For the slope to equal the value of , Choose one answer. A. the acceleration should be on the vertical axis and the mass ratio should be on the horizontal axis B. the acceleration should be on the horizontal axis and the mass ratio should be on the vertical axis 3. A glider with mass is pulled on an air track by a string attached to a falling mass as shown in Figure 7.1 in the lab manual. Which one of the following is the correctly scaled free body diagram for the falling mass ? Choose one answer. (a) (b) (c) (d) (e)

Explanation / Answer

1. Mass Ratio has no Units ( it is a ratio and a ratio never has any units) Option- c is correct 2. we have, a = [m/(m+M)] g a/[m/(m+M)] = g For the slope to be equal to g, clearly acceleration should be the vertical axis and mass ratio on horizontal axis Option - A is correct 3.
