mere b help ker dy koi mai to 1st ques pe he atak gai hun

In my opinion, first question can be solved by this formula F= qv *B sin teta

q= proton = 1.6*10^-19

v= speed

sin teta = angle

T= B

Question NO 1:

q=1.6*10^-19 this is charge on proton

v= 3.00*10^6

angle = sin 37 degree = 1.601

B= 0.300

F= qv*B sin teta.  Now puting the value in this formula you can easily find the answer

Question no 3

hm u are right in my first question solution I have F= 865.10^-16

brother's gives your idea for the second question.... what I do with that?

The changing magnetic field in the coil induces voltage. In this way, information sotred magnetically on the disk is converted to electric signals.

This is the answer of q.2
