Answer:
Explanation:
we know that electric field is given as
from the figure electric field c and electric field a CANCEL OUT EACH OTHER
so, we have E_B and E_D is toward -q direction
Answer:
E = 7.70 × 10⁻²⁸ J
Explanation:
Energy = hf
h = Planck's constant = 6.63 × 10⁻³⁴ J.s
f = frequency = 1160 KHz = 1.16 × 10⁶ Hz
E = (6.63 × 10⁻³⁴ × 1.16 × 10⁶)
E = 7.70 × 10⁻²⁸ J
