Can i get some ? i really need it!

If angle "a" is 25°, angle "b" is: a) equal to angle c b) less than angle c c) greater than angle c

)consider two positively charged particles, one of charge q0 (particle 0) fixed at the origin, and another of charge q1 (particle 1) fixed on the y-axis at (0,d1,0). what is the net force f⃗ on particle 0 due to particle 1?

Aforce is a vector quantity because it has both?
