Answer:
Because the disturbances are in opposite directions for this superposition, the resulting amplitude is zero for pure destructive interference
Explanation:
When we need to calculate the resultant value of them.......
Explanation:
r^2= 9×10^9 × 5.87×5.87×10^-16 / 64.9
=47.7× 10^-8
so taking sq. root
r = 6.9 ×10^-4 m
or
r= 6.9×10^ -2 cm
this gives the required seperation
An entrepreneur would like their customers to come back, with this the customer service must be good. The owner’s workers must be kind & fair to the consumers. However good your product or service is, the simple truth is that no-one will buy it if they don't want it or believe they don't need it.
