Answer:
Explanation:
Given data
Mass m=2.46×10⁻²⁶kg
Voltage V=270 V
Magnetic field B=0.5353 T
To find
Radius r
Solution
By using conservation of energy to find speed of charge
Substitute the given values
So the radius can be find as:
Substitute the values
Answer:B
nice calculations!
momentum p= m x v = 15 x -4 = -60 N.s
