Answer:
The net force acting on the person is, F = 560 N
Explanation:
Given data,
The downward acceleration of the elevator, a = 1.8 m/s²
The weight of the person is, W = mg
= 686 N
Therefore the mass of the person,
m = W /g
= 686 / 9.8
= 70 kg
The net force acting on the person,
F = mg - ma
= 686 - 70 x 1.8
= 560 N
Hence, the net force acting on the person is, F = 560 N

Answer:
E= 2.158× 10*5N/C
Explanation:
K= 8.99×10*9, q= 6×10*-6C, d= 0.5m
E= kq/d*2
E= (8.99×10*9× 6×10*-6)/0.5*2
E= 215760
E= 2.158 ×10*5N/C
