Answer:
The force exerted on a moving charge is
.
Explanation:
We have,
Charge, 
Magnetic field, 
Velocity of charged particle, 
Angle through the magnetic field, 
It is required to find the force exerted on a moving charge. Due to the motion in charge, magnetic force acts on it. It can be given by :

Plugging all values above

So, force exerted on a moving charge is
.
Answer:
Total pressure exerted at bottom = 119785.71 N/m^2
Explanation:
given data:
volume of water in bottle = 150 L = 0.35 m^3
Area of bottle = 2 ft^2
density of water = 1000 kg/m
Absolute pressure on bottom of bottle will be sum of atmospheric pressure and pressure due to water
Pressure due to water P = F/A
F, force exerted by water = mg
m, mass of water = density * volume
= 1000*0.350 = 350 kg
F = 350*9.8 = 3430 N
A = 2 ft^2 = 0.1858 m^2
so, pressure P = 3430/ 0.1858 = 18460.71 N/m^2
Atmospheric pressure
At sea level atmospheric pressure is 101325 Pa
Total pressure exerted at bottom = 18460.71 + 101325 = 119785.71 N/m^2
Total pressure exerted at bottom = 119785.71 N/m^2
Answer:
17 m
Explanation:
Work done is the product of force and perpendicular distance moved, therefore, expressed as
W=Fd
Where F represent the applied force, d is perpendicular distance and W is work done.
Making d the subject of the formula then

Substituting 68 J for work and 4 N for force then

Therefore, the distance is equivalent to 17 m
Most likely gravity, because the gravity would pull it off course or wobble.
Answer:
0.084 kg
Explanation:
I = 0.80 N-s (East wards) = 0.80 i N-s
u = 3.8 m/s = - 3.8 i m/s
v = 5.7 m/s = 5.7 i m/s
Let m be the mass of bat.
I = m (v - u)
0.8 i = m ( 5.7 i + 3.8 i)
0.8 i = m x 9.5 i
m = 0.084 kg
