Answer:
option (B)
Explanation:
mass of proton, m = m
charge of proton, q = e
Time period, T = T
Initially the speed of proton is v.
The time period of the proton when it is moving in magnetic field perpendicular to the direction of magnetic field is given by
Where, r be the radius of circular path.
The relation between r and the speed v is given by
Where, B be the strength of magnetic field. Substitute this value of r in the expression of time period
Here, we observe that the expression for the time period is independent to v and r so, as we change the velocity, the time period remains same.

Answer:
A) A wedge
B) The efficiency of the machine is 50%
Explanation:
The type of simple machine Scott used is the wedge
A) A wedge is a simple machine that consists of a long thick metal or wood stem that tapers to a thin (Relatively sharp) end. It is used for a splitting, tightening, and lifting.
An example of a wedge is an axe
B) The efficiency of a machine is given approximately as the ratio of the work output to the work input as follows;
The amount of input energy the axe uses = 200 Joules
The amount of output work Scott receives from the axe = 100 Joules
Therefore, the efficiency of the machine, η, is given as follows;
The efficiency of the machine, η = 50%
Answer:
SO THE CENTRIPETAL FORCE IS 158N
Explanation:
m=69.5kg
v=8.00m/s
r=28.2m
Fc=?
as we know that
Fc=mv²/r
putting values
Fc=69.5kg×(8.00m/s)²/28.2m
Fc=(69.5kg×64m²/s²)/28.2m
Fc=(4448kgm²/s²)/28.2m
Fc=157.7N≈158N
