Question

15. The school bags are generally provided with the road is because
(a) It will spread the force of the bag over the lansarea of the shoulder of the
child producing large pressure.
(b) It will spread the force of the bag over the large area of the shoulder of the
child producing less pressure.
() It has become a trend among the students to carry the boys with wide stripe
() It will spread the force of the bag over the small area of the shoulder of the
child producing less pressure.​

Answer 1

Answer:

Given:

School bags are provided with a wide stripe.

Explanation:

In school days, students have to carry many things . For example :

1. Books of every subject
2. Exercise copies
3. Tiffin boxes
4. Water bottles
5. Other accessories like pencil boxes and geometry boxes.

So their bags tend to be very heavy.

Hence bags exert a high force on the shoulder of the child carrying the bag .

Mathematical significance:

We know that Pressure is a quantity obtained by dividing force by area of contact.

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

where P is Pressure, F is force and A is area of contact.

Now, for constant force,

P ∝ 1/A

So, if a wide Stripe is provided with the bags, then the pressure exerted on the shoulder of the child will be less.

Hence the child will feel less distress in carrying the bag.

SO OPTION B) IS CORRECT.

Answer 2

Answer:

$\huge\boxed{ \fcolorbox{blue}{yellow}{answer}}.$

School bags are provided with a wide stripe.

Explanation:

In school days, students have to carry many things . For example :

Books of every subject

Tiffin boxes

Water bottles

Other accessories like pencil boxes and geometry boxes.

So their bags tend to be very heavy.

Hence bags exert a high force on the shoulder of the child carrying the bag .

Mathematical significance:

We know that Pressure is a quantity obtained by dividing force by area of contact.

P \: = \frac{F}{A}P=AF

where P is Pressure, F is force and A is area of contact.

Now, for constant force,

P ∝ 1/A

So, if a wide Stripe is provided with the bags, then the pressure exerted on the shoulder of the child will be less.

Hence the child will feel less distress in carrying the bag.

SO OPTION B) IS CORRECT.
