I have some trouble in exercise 1 and 2.

Exercise 1 says: There is a load q=-1μC in point A in axis x that is 0.15m form point O on the start of the axis. In the same time a second load Q is in point B of the axis Z that is 0.10m from point O on the start of the axis. The loads q and Q are moving with speeds u1 and u2. The direction of the two speed is shown on the graph, while we know that |u1|=10^7 m/s and |u2|=5*10^7 m/s. If the magnectic field on the point O is equal with zero calculate: a) The value and the sign for the load Q
and b) The electric field on point O

Exercise 2 says: Three loads Q1=-1nC, Q2=+2nC and Q3 are on axis x an specifically Q1 on the start of the axis, Q2 on the point X=0.1m and Q3 on the point X=0.3m

The loads Q1 an Q2 are moving with speeds u1 and u2, while the load Q3 is not moving. |u1|=|u2|=10^8 m/s.
If the total electric force that is being wielded on load Q1 equals zero calculate:
A) The value and the sign for load Q3
B)The magnetic force on load Q1.

What do you want us to do about it?

What parts of the questions are you struggling with?

Have you attempted them yourself?

All of it. Of course i attempted to solve them but there are not similar exercises in my notes so i don't know how to solve them. I'm not looking for someone to solve them for me just maybe some formulas i can use or any help at all.
