If a man wants to move a car of weight 3000N a distance of 4m. Calculate the work done?

3000 times 4=12000

Explanation: the work is calculated by multiplying the force by the amount of movement of an object (W = F * d). A force of 10 newtons, that moves an object 3 meters, does 30 n-m of work. A newton-meter is the same thing as a joule, so the units for work are the same as those for energy – joules.

using he formula Work done F×D

the answer is to check all of them! they all apply well at least i think so!

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
