Given Information:
Resistance = R = 250 Ω
Voltage = V = 3 V
Tolerance = ±5%
Required Information:
Maximum current = Imax = ?
Minimum current = Imin = ?
Answer:
Imax = 12.6 uA
Imin = 11.4 uA
Explanation:
As we know from Ohm's law
I = V/R
The current will be maximum when R is minimum and the current will be minimum when R is maximum
Rmax = 250,000 + 0.05*250,000
Rmax = 250,000 + 12500
Rmax = 262500 Ω
Rmin = 250,000 - 0.05*250,000
Rmin = 250,000 - 12500
Rmin = 237500 Ω
Imax = V/Rmin
Imax = 3/237500
Imax = 12.6 uA
Imin = V/Rmax
Imin = 3/262500
Imin = 11.4 uA
Answer : 
Explanation :
It is given that,
Charge, 
Velocity of Aircraft, 
(in west)
Magnetic field, 
( in north )
Using the relation as :
Magnetic force is ,
Using Right hand thumb rule, the direction of force is in the plane perpendicular to the velocity and the magnetic field i.e. 
.
I think it may be c, 1.7 v. I work with electricity a lot.
The horizontal component is 2.0 cos(30°) = 1.732 m/s²
The vertical component is 2.0 sin(30°) = 1 m/s²
