Answer:
16.5 m
Explanation:
Given,
Magnetic field = 0.02 T
radius of electron = 9 mm
speed of electron = speed of proton
radius of proton = ?
We know,
.........(1)
using newton second law
equating Force due to electron and proton
m_ e = 9.1 x 10⁻³¹ Kg and m_p = 1.67 x 10⁻²⁷ Kg
Hence, the radius of proton is equal to 16.5 m.
Answer:
its 1st one
the relative strength with which an element attracts electrons in a chemical bond
Answer:
Explanation:
Given
mass of projectile
initial horizontal speed
height
Considering vertical motion
velocity gained by projectile during 26.7 m motion
v=final velocity
u=initial velocity
a=acceleration
s=displacement
Horizontal velocity will remain same as there is no acceleration
final velocity
Initial kinetic Energy
Final Kinetic Energy
Work done by all the force is equal to change in kinetic Energy of object
Work done by gravity is
The first choice is closest to being an accurate description.
