Answer:6km/sec
Explanation: Acceleration = Change in velocity / Time
Change in velocity = 60km/h minus 30km/hr
Time = 5seconds
Explanation:
It is given that,
Diameter of loops, d = 48 cm = 0.48 m
Radius of the loop, r = 0.24 m
Current carried in the loop, I = 4.5 A
Distance between loops, x = 30 cm = 0.3 m
Speed of the proton, v = 2600 m/s
We know that the magnetic field at the midway of the coils is given by :
Let F is the magnetic force these loops exert on the proton just after it is fired. It is given by :
So, the magnetic force these loops exert on the proton is . Hence, this is the required solution.
The object takes 8 s to reach a velocity of 48 m/s south
Explanation:
Since the motion of the object is a uniformly accelerated motion, we can use the following suvat equation:
v = u + at
where
v is the velocity at time t
u is the initial velocity
a is the acceleration
t is the time
For the object in this problem, choosing south as positive direction, we have:
u = 16 m/s
v = 48 m/s
So we can solve the equation for t to find the time taken for the velocity to change from 16 m/s to 48 m/s:
