voltage difference, V, between the plates. Answer =- . 30 pts. (17) The initial potential d potential difference, V, between the plates. ifference between a pair of oppositely charged parallel , d, between the plates is 700.0 V. (The 700 V battery is then removed.) pates is tripled without altering the charge, Q, on the plates, then calcul plates is Answer Chapter 20- Magnetism 15 pts. (18) An electron moves with a speed of 4.0 x 10 m/s in a region where its velocity is perpendicular to the direction of the magnetic field. The force on the electro is 5.0x 10" Newtons. Calculate the magnitude of the magnetic field, in units of Tesla B=1.25 × 10-18T B = 18.75 T ? 8.0x 1017T B=2.50 x10"T B 2.6 T B=3.2 × 10-26T B = 4.17 × 10-19T B =7.81 T B 9.6 x 10 2 T

Explanation / Answer

sol 17.. when battery is removed then charge on capacitor remains constant.

voltage = charge / capacitance

or 700= Q/C

now when spacing d is tripled then capacitance becomes one third as it is inversely proportional to d.

so in new situation

V = Q /(C/3) = 3*Q/C = 3*700 = 2100 volt

so new potential difference is 2100 volt
