Step 1

972 \times 10^{24} \times 1.47 \times 10^7 \times v_{\text{perihelion}} = 5.972 \times 10^{24} \times 1.52 \times 10^7 \times 29.29 \times 10^3 \] \[ v_{\text{perihelion}} = \frac{5.972 \times 1.52 \times 29.29}{1.47} \times 10^6 \] \[ v_{\text{perihelion}} = 33.34 Show more…

00:01 Hello students, let us look on this question.

00:02 So, in this question we have given the sun in the mid, we have given this is sun and this is the distance that is given to us is r a and this is the r p, okay.

00:14 This is a p g and p g distances both are given to us and this is the any orbital particle moving with the speed of v a and here moving with the speed of v p, this is v p, okay.

00:28 And we have given some values here.

00:30 First of all we have given distance r p, r p equal to 1 .47 into 10 raise to the power 7 kilometer.

00:39 Then we have given the r a equal to 1 .52 into 10 raise to the power 7 kilometer.

00:45 Then we have given the speed of the point a that is equal to 29 .29 into 10 raise to the power 3 meter per second.

00:53 Then the mass of the e is equal to simply given to us 5 .922 into 10 raise to the power 24 kg.

01:03 And finally, we have given the mass of the s is equal to 1 .989 into 10 raise to the power 30 kg.

01:10 These are the values that is given to us.

01:12 And we know in the circular orbit is we can set all the points.

01:16 If i am talking about the first of all the angular momentum, if i am talking about the angular momentum that is angular momentum and second thing is total energy, total energy.

01:32 So, we can say both are conserved in this circular motion, both are conserved...
