Final Answer:
In the diagram, there are more electric field lines pointing towards charge 1 (+Q1) than towards charge 2 (-Q2). This means that charge 1 has the larger magnitude.
Step-by-step explanation:
Electric field lines are a way of visualizing the strength and direction of an electric field. The more electric field lines there are, the stronger the electric field. The direction of the electric field lines is always away from positive charges and towards negative charges.
In the diagram above, there are more electric field lines pointing towards charge 1 than towards charge 2. This means that charge 1 has the larger magnitude. In other words, charge 1 is stronger than charge 2.
