Three point charges lie in the xy-plane: with q1= 86 μc at origin (0,0), q2= 32μc at the point (2.5m, 0), and q3=−53μc at the point (1.5m, 2.2m). find the net force on q1?

At an oceanside nuclear power plant, seawater is used as part of the cooling system. this raises the temperature of the water that is discharged back into the ocean. the amount that the water temperature is raised has a uniform distribution over the interval from 10° to 25° c. what is the standard deviation of the temperature increase?
