An object has a velocity of 5 meters per second. to the nearest kilometer , how many kilometers will it travel in 3 days

Assuming that the object doesn't rest, and keeps that pace going for three days straight, first you need to calculate the the amount of meters the object can travel in one day. And to find that out you need to find the number of meters it travels per minute, which is 5 times 60, which is 300. Then calculate how far it travels per hour, which is 300 times 60, which is 18,000. Then find out how far it travels in a day, which is 18,000 times 24, which is 432,000. Then to find how many meters it travels in 3 days you multiply 432,000 by 3 which is 1,296,000. Then to find how many kilometers that is, you divide that by 1,000, which comes out to be 1296 kilometers in 3 days.

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
