​

Answer 1

Answer:

• Length of string is 149 cm or 1.49 m.

Explanation:

Given :-

• Bob of a simple pendulum have diameter 2 cm.

• Effective length is 1.5 m.

To find :-

• Length of the string

Solution :-

Effective length = Length of the string + radius

Radius = Diameter/2

Radius = 2/2

Radius = 1 cm

Effective length = 1.5 m

Effective length = 1.5 × 100 cm

∴ Effective length = 150 cm

Length of string = Effective length - Radius

Length of string = 150 - 1

Length of string = 149

Length of string = 149/100 cm = 1/49 m

∴ Length of string is 149 cm or 1.49 m.
