Answer:
he spring provides the controlling torque. The air friction induces the damping torque, which opposes the movement of the coil. The repulsion type instrument is a non-polarized instrument, i.e., free from the direction of current passes through it. Thus, it is used for both AC and DC
Answer:
528398.4375 N/C opposite to the direction of the proton

288.24609375 N/C in the same direction of the motion of the electron
Explanation:
t = Time taken
u = Initial velocity = 0
v = Final velocity = 
s = Displacement = 3.2 cm
a = Acceleration
Mass of electron = 
Mass of electron = 
q = Charge of particle = 

Electric field is given by

The electric field is 528398.4375 N/C opposite to the direction of the proton

The time taken is 

The electric field is 288.24609375 N/C in the same direction of the motion of the electron

Answer:
Option C=> π+.
Explanation:
Just as it is given in the question above, we can see that the addition or combination of proton and neutron gives what is known as QUARKS.
Quarks are not easily measured because one can not see and study a quark independently; quarks move in multiples together.
The study of Quarks is very important in physics because they relate very well with electromagnetic force, strong force, weak force and Gravitational force.
"...When the remaining quarks combine to form a single particle, it is a π+".
π+ is a meson or a pion and it contains quarks and anti-quarks too
