Answer:
Calculate 'R' of convex mirror and height of the real image
the radius of the convex mirror is 48cm
Explanation:
Distance between convex and concave mirror is =60cm
Radius of the concave mirror (R) = 200cm
For the concave mirror, u = ∞
V = {R}/{2}=100cm
The object for the convex mirror and the final image is on the pole of the concave mirror, and distance between convex and concave mirror is 60cm
u_1=60-100 =-40cm
Object will be behind the convex mirror
1/f=1/40+1/60
f=24cms
the radius of the convex mirror is 48cm
Answer:

Explanation:
B at point 7.0 cm radially outward is to find out?
Now for field strength in case of parallel plates in given as



For the second part as Capacitor is fully charged no more flow of current could take place hence
I= Current =o
so B = 0
6. Drop to one quarter of its original value
Answer:
Two mass nuclei are joined to form one nucleus
Explanation:
As the name implies "fusion", it is the joining of lighter nucleus to form a heavier nucleus to produce energy
