Dear Student,
Electrostatic force is the Coulomb force acting between two static charged particles. It can be force of attraction as well as repulsion. Electrostatic attraction occurs between opposite charges and electrostatic repulsion occurs between similar charges.
Electromagnetic forces also acts between charged particle, but these charged particles are moving which induces magnetic field in them. So, electromagnetic forces comprises of both electrostatic and magnetic forces. They are also attractive as well as repulsive.
