Answer:
Time period of the motion will remain the same while the amplitude of the motion will change
Explanation:
As we know that time period of oscillation of spring block system is given as
now we know that
M = mass of the object
k = spring constant
So here we know that the time period is independent of the gravity
while the maximum displacement of the spring from its mean position will depends on the gravity as
so we can say that
Time period of the motion will remain the same while the amplitude of the motion will change
Answer:
(A). The speed of the ions is
(B). The radius of curvature of a singly charged lithium ion is
Explanation:
Given that,
Electric field = 60000 N/C
Magnetic field = 0.0500 T
(A). We need to calculate the velocity
For no deflection
(B). We need to calculate the radius
Using magnetic force balance by centripetal force
Put the value into the formula
Hence, (A). The speed of the ions is
(B). The radius of curvature of a singly charged lithium ion is
