Hello everyone.
00:02
In this question it is given that venus planet is revolving around the sun in a circular orbit, where the radius is r is equal to 108 .2 million kilometers.
00:22
We can write this 108 .2 multiply by 10 to the power of 6 km or we can also write 108 .2.
00:34
Multiply by 10 to the power of 9 meter.
00:39
So this is the radius of the orbit in which the planet venus is revolving.
00:46
We have also given the time period of this orbit, this revolution.
00:52
The time period is 0 .6152 years.
01:01
We can convert this into second as 0 .6252 multiply by 365, multiply by 24, multiply by 60 and multiply by 60.
01:20
On solving this, we get time period is equal to 1 .9 multiply by 10 to 10 to the power of 7 second.
01:31
So this is the time period.
01:34
We have asked this centripetal acceleration, that means the acceleration of planet venus towards the sun.
01:41
So we have to solve centripetal acceleration...
