Look it up or take your own freaking notes. :) The electric field strength (or magnitude of the electric field) is defined as the force per unit charge or: (6).

The International Baccalaureate Organization (known as the IB) offers four high-quality electromagnetism described the behaviour of electric charge and unified Force and field strength (see Physics sub-topics 2.2, 5.1, 6.1 and 10.1). 16 Nov 2018 Electricity and Magnetism & Fields (HL) & Electromagnetic Induction (HL) notes 5; IB Physics notes 10; IB Physics notes 11; 5.1 - Electric fields 9 Feb 2018 Read our set of IB Physics notes and our free study guide for the best resources Magnetic, and Gravitational · Video: Electric Force and Field.The electric field strength at a point in an electric field is the force per unit charge acting on a small positive test charge placed at that point. To calculate the field strength at point p, imagine a 1C (positive) charge to be placed at p and then use Coulomb's law. 8 Apr 2017 Define field strength as force per unit charge. Note: Electric field lines aren't actually mentioned in the subject guide but I see no reason to leave them out. Electric field: space that surrounds a charge and influences small test charges, which do not disturb the field. No electric field inside a conducting sphere.? The force felt per unit charge by a small positive test Electric fields exist around charges and combinations of Electric field strength (E) is the force per unit charge experienced by a positive test change placed in a field. where F is the force, q1 and q2 are the charge of the two objects (usually the same when considering two electrons), and r is the radius/distance between the two charges.
