If the diameter of the pulley is 6 inches, length of pointer is 10 inches and distance travelled by pointer is 5 inches. Calculate the actual growth in length of plant.

A

3 inches

B

6 inches

C

12 inches

D

30 inches

Text Solution

Verified by Experts

option are wrong, (correct Ans = 1.5 inches).
[Diameter of pulley = 6 inches.
`therefore` radius of pulley = 3 inches
Actual growth in length `=("Distance travelled by the xx Radium of the pulley")/("Lenght of the pointer")`
`=(5xx3)/(10)=1.5`
