Two particles of equal masses (m=5.5x10-15 kg) are released from rest with a distance between them equal to 1 m. if particle a has a charge of 12 μc and particle b has a charge of 60 μc, what is the speed of particle b at the instant when the particles are 3m apart?

To solve this problem it is necessary to apply the law of conservation of Energy and the law of Coulomb.

This way we have to

Where,

= Potential Electric Energy

Kinetic Energy

Therefore,

Replacing we have that

Therefore the speed of particle B at the instant is

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
