Question

There are two school bags A & B. Bag A is provided with a broader strap, while bag B is provided with a thinner strap. For the same load, a school boy likes bag A as he is comfortable with it; but with bag B, he develops a pain in his shoulders. This is because:

• A. Bag A has a broader strap than B, due to which the pressure felt is less for the same load.
• B. Bag B has a thinner strap than A, due to which the pressure felt is more for the same load.
• C. Both A & B
• D. None of these

Answer 1

The correct option is C

Both A & B

$P=\frac{F}{A}$;

Since the pressure is the force per unit area, in bag A the pressure developed would be less than B for the same load as the straps are broader.
