The figure below shows lines of electric field in a certain region. Which of the following statements are true? Choose all that apply. 3 2. 4 O Rates of change of electric potential at points (3) and (4) are comparable. O Charged particles experiences an acceleration of the smallest magnitude at point (1). O The magnitude of electric field at point (2) is smaller than that at point (3). O Work done by electric field while moving a neutron from point (1) to point (2) is negative.Consider a spherical object made of unknown material that carries an excess positive charge Q. Electric potential in the center of the object is the same as the electric potential at its surface. O The object is made of a dielectric material The object is made of a conducing material
