Answer 1

Given:-

• An iron ball is placed between two wooden blocks along a centimetre scale.

Find:-

• Reading on metre scale at A
• Reading on metre scale at B
• Diameter of iron ball.

Solution:-

(a) $\red{\textsf{Reading on metre scale at A:}}$

Here, from the fig.

we, can see block A is coinciding on scale at 3.3cm

So, reading on metre scale at A is 3.3cm

(b) $\red{\textsf{Reading on metre scale at B:}}$

Here, from the fig.

we, can see block B js coinciding on scale at 5.9cm

So, reading on metre scale at B is 5.9cm

(c) $\red{\textsf{Diameter of iron ball:}}$

Here, from the fig.

we, can calculate it's radius which is 1.5cm

we, know that Diameter = 2×Radius

So,

→ Diameter = 2×1.5

→ Diameter = 3cm

Hence, Diameter if iron ball is 3cm
