Answer:
So it floats
Explanation:
m =3893.40 /10 = 389.340kg (if i use g= 10 not 9.81 -use 9.81 if your syllabus says so)
v = 4.60 m cube
389.340/4.60 =84.64
as density less than that of water 90
so it floats
Answer:
d
Explanation:
this is just common sense, why did you even need to ask?
The force you are mentioning is called Laurentz Force.
By definition, F = qvB, where q is the charge of the particle, v is the velocity, and B is the field intensity.
Therefore, the particle must be of moving charge.
