Question

Part A)

The figure shows the E field in the plane of two point charges. Select all the statements below that are correct.  
A) |Q1| is larger than |Q2|.
B) Q1 and Q2 have the same sign.
C) A negative charge placed at a would accelerate right.
D) A positive charge at a would accelerate right.
E) The magnitude of E is the same at a and at b.
F) Q1 is negative.

Part B)

The figure shows the equipotential contours due to three point charges, labelled in volts.
Select T-True, F-False for each of the statements below.  

1) The charge located at (0,0) is greater than the charge located at (-5,5).

2) 118.1 J of work is done to move a charge of 1 coulomb from c to d along the contour.

3) The potential at b is greater than the potential at a.

4) The electric field at e is directed normal to the 221.7 V contour and towards the 312.1 V contour.

5) Two of the charges are positive and one is negative.

6) A charge released from rest on one of these contours will move along the contour.

Explanation / Answer

A-correct since more field lines coming through q1 than q2.

B-Incorrect since from one charge field line emerging means positive charge and so the second one is negative.

C-incorrect since q1 is negative and q2 is positive

D-yes because of the same above reason

E- incorrect since distance is different for both points

F-yes q1 is negative since field lines merging in it

As per chegg policy i need to answer only 3 subparts but i solved 6.
