Electric Charges & Fields | Electric Field Lines All the best! 1. The figure shows the electric field lines due to two charges. What is the nature of the two charges? q1 is positive while q2 is negative q1 is negative while q2 is positive Both positive Both negative None 2. The figure is a plot of electric lines of force due to two charges q1 and q2. Identify the two charges. Both positive Both negative Upper positive and lower negative Upper negative and lower positive None 3. Figure shows the electric lines of force emerging from a charged body. If electric field at A and B are EA and EB respectively, then-A. EA > EB B. EA < EB C. EA = EB D. Data Insufficient Option (A) Option (B) Option (C) Option (D) None 4. Figure shows three electric field lines. If FA, FB and FC are forces on a test charge q at positions A, B and C respectively, then- A. FA > FB > FC B. FA < FB < FC C. FA > FB = FC D. FA < FB = FC Option (A) Option (B) Option (C) Option (D) None 5. A metallic sphere is placed in a uniform electric field as shown. Which path is followed by the lines of force shown in the figure? Path a Path b Path c Path d None 6. Which of the following is NOT a property of electrostatic field lines? Field lines are continuous curves in free space without any break Two field lines cannot intersect each other Field lines start at positive charge and end at negative charge Electrostatic field lines form closed loops None 7. Which option is incorrect for electrostatic field? It is conservative in nature It may be non-conservative It follows inverse square law It produces lengthwise contraction between dissimilar charges None 8. Assertion- Electric lines of force cross each other.Reason- Electric field at a point superimposes to give one resultant electric field. Both Assertion and Reason are correct and Reason is the correct explanation of Assertion Both Assertion and Reason are correct but Reason is NOT the correct explanation of Assertion Assertion is false and Reason is true Assertion is false and Reason is also false None 1 out of 8 Time's up
