Answer:
C. Electronic charges have electric fields surrounding them that allow them to exert forces on other objects without touching them.
Explanation:
All the electric charges have electric field in the region surrounding them
This electric field is given as
above formula is the electric field due to a point charge in the surrounding region of it.
Now due to this electric field when other charges comes into this region they will experience electric force on them which is given as
due to above reason two charges either attract or repel each other
so correct answer will be
C. Electronic charges have electric fields surrounding them that allow them to exert forces on other objects without touching them.

Answer:
angular range is ( 0.681 rad , 0.35 rad )
Explanation:
given data
wavelength λ = 380 nm = 380 × m
wavelength λ = 700 nm = 700 × m
to find out
angular range of the first-order
solution
we will apply here slit experiment equation that is
d sinθ = m λ ...........1
here m is 1 for single slit and d is =
so put here value in equation 1 for 380 nm
we get
d sinθ = m λ
sinθ = 1 × 380 ×
θ = 0.35 rad
and for 700 nm
we get
d sinθ = m λ
sinθ = 1 × 700 ×
θ = 0.681 rad
so angular range is ( 0.681 rad , 0.35 rad )
