the sphere of influence of the density of the customer population of a service centre is high near the service centre but decrease with increasing distance due to the frictional effects of the distance in public hospital
This means that the service centre is likely to attract more customers from nearby areas compared to those located further away. As distance increases, people may be less willing to travel to the service centre due to the inconvenience and additional time and cost involved.

Therefore, the density of the customer population is highest near the service centre and gradually decreases as distance from the centre increases.
