* 100 % ) - the 3) A voltage of 5.0 V and a current of 1.2 A is applied to a solenoid that is 25 cm long (a diagram of the actual solenoid is shown below). A proton travels at 525 km/s [downwards], also shown below. The coil is turned on when the proton arrives at the centre inside the coil. Determine the magnitude and direction of the force acting on the proton at that time. Indicate the direction of the coil's magnetic field in the diagram for full marks. [ 3 TI ] 14
