Question

A particle of mass 0.5 GM moving along x axis is located at x 1 is equal to 15 m t1 is equal to 5 second and at X2 is equal to 33 at 30 second it's velocity is​

Answer 1

Answer:

0.327 weber/meter square

Explanation:

we know force =mass×acceleration due to gravity

=0.5×9.8m/s^2

thus force=4.9N

also we know force =q[v×B]

B=4.9/2.5×6×10×10×10×10

=0.327 weber per meter square

Answer 2

Answer: 2.25 m/s

Explanation:  As we know that average velocity = total displacement covered / total time taken

i.e. <v> = $\frac{33-15}{13-5}$ = $\frac{18}{8}$ = $\frac{9}{4}$ = 2.25 m/s

Note: Here displacement cannot be added.
