1(a) 1(b) 1(c) An isolated conducting sphere is charged positively. The sphere is surrounded-by air. The electric field near the surface of this sphere is 100 V/m. The radius of this sphere is 1 cm. Calculate the total charge on the sphere. Calculate the total electric force in vector form acting on a charge of -10 nC, if the total electric field, Er, at the point of location of this charge is a sum of two individual components, E₁ E2, where E,= -15-250 (V/m) and E₂=-35-50, (V/m). Two identical capacitors (with capacitance of 10 nF each) are connected in series and attached to a battery of 200 V. Find the total charge stored in these two capacitors.
