The concept required to solve this problem is the properties of electric field and the field lines.
Use the properties of the electric field to identify the statement is true or false.
The properties of electric field are as follows:
The electric field points away from positive charge and towards a negative charge.
The electric field direction is given by a force on positive test charge.
The more number of field lines or greater number density of electric field lines implies greater magnitude of electric field or charge.
Like charges repel and unlike charges attract.
(1)
The electric field lines point away from a positive charge and towards a negative charge. Refer the figure in the question, the electric field lines point away from charge and towards the charge . So, the charge is positive and charge is negative. Thus, the charges have opposite sign. Hence, and don’t have the same sign.
(2)
The electric field direction is given by a force on positive test charge. The electric field points towards right at c. So, the force on a positive charge at c is therefore towards right. The acceleration is in the direction of force acting on the particle. Thus, the charge would accelerate to the right.
(3)
The greater number density of electric field lines implies greater magnitude of electric field. The spacing in between is more if number density is less. The spacing is more at point b as compared to a. So, the number density of electric field lines is not same at a and b. Thus, the magnitude of the electric field is not same at a and b.
(4)
The electric field direction is given by a force on positive test charge. The electric field points towards left at a. So, the force on a positive charge at a is therefore towards left. But on a left charge force is opposite so it is towards right on negative charge. The acceleration is in the direction of force acting on the particle. Thus, the charge would accelerate to the right.
(5)
The electric field lines point away from a positive charge and towards a negative charge. Refer the figure, the electric field lines point away from charge and towards the charge . Thus, the charge is positive and charge is negative.
(6)
The number of electric field lines from are more in number than at . Refer the figure, the number of lines originating from are 18 and at are 13. So, greater number implies greater electric field or greater magnitude of charge.
