A conducting bar rests to complete a circuit and immersed on a uniform magnetic field of B = 0.44 T. It is made of silver, has a length of 0.56 m, and diameter of 9 mm. The resistor on the circuit has 24 ohms resistance. Calculate the initial acceleration (in m/SZ) of the bar. when the resistor's resistance is decreased instantaneously to 3 ohms (due to short circuit). (Hint: you may need to calculate the maximum voltage first where the bar is in the state of equilibrium). Note: Final answer in ZERO decimal place. Use conventional current. Use pi = 3.14. Use the following: resistivity of silver = 1.47x10'811m density of silver : 10500 kq/m3
